webkitgtk3: upgrade 2.50.6 -> 2.52.4

fix -Werror=poison-system-directories in g-ir-scanner

CMake's pkg_check_modules stores the bare INCLUDEDIR variable (/usr/include)
on imported targets' INTERFACE_INCLUDE_DIRECTORIES. WebKit's FindGI.cmake
forwards every interface include dir to g-ir-scanner as -I, so the
introspection compile is invoked with -I/usr/include. With a GCC configured
with --enable-poison-system-directories=error (as in OpenEmbedded cross gcc):

  cc1: error: include location "/usr/include" is unsafe for cross-compilation
  [-Werror=poison-system-directories]

g-ir-scanner only extracts -D/-I/-U from CFLAGS (not -Wno-error flags), so the
warning cannot be relaxed via the recipe CFLAGS. Filter the bare host system
include directories (/usr/include, /usr/local/include) out of the scanner flags
in FindGI.cmake instead; the sysroot include path is added automatically.

filter bare system include dirs from gir generator expr

The FindGI g-ir-scanner fix only filtered /usr/include from the dependency
loop that builds scanner_flags. The include dirs also reach the scanner via
the per-target INTERFACE_INCLUDE_DIRECTORIES generator expression that is
joined into -I flags on the g-ir-scanner command line, which was left
unfiltered.

JavaScriptCore-4.1.gir happens to carry no bare /usr/include on its target
so it succeeded, but WebKit2/WebKitGTK does, so the WebKitGTK introspection
still failed under the OpenEmbedded cross compiler:

  cc1: error: include location "/usr/include" is unsafe for cross-compilation
  [-Werror=poison-system-directories]

Filter /usr/include and /usr/local/include out of the target_inc generator
expression with $<FILTER:...,EXCLUDE,...> too.

+Subject: [PATCH] FindGI: drop bare system include dirs from g-ir-scanner flags
+
+When cross-compiling, CMake's pkg_check_modules records the bare pkg-config
+INCLUDEDIR variable (e.g. /usr/include) on the imported targets'
+INTERFACE_INCLUDE_DIRECTORIES. FindGI forwards every interface include dir
+to g-ir-scanner as -I, so the introspection compile is invoked with a bare
+-I/usr/include. With a GCC configured with
+--enable-poison-system-directories=error (as in OpenEmbedded) this is a hard
+error:
+
+  cc1: error: include location "/usr/include" is unsafe for cross-compilation
+  [-Werror=poison-system-directories]
+
+g-ir-scanner does not forward the recipe's -Wno-error=poison-system-directories
+(it only extracts -D/-I/-U from CFLAGS), so the warning cannot be relaxed from
+the recipe. Filter the bare host system include directories out instead; the
+proper sysroot include path is added by the compiler driver automatically, so
+dropping them is safe.
+
+The include dirs reach the scanner through two paths, both of which must be
+filtered:
+
+  * the dependency loop that appends to scanner_flags, and
+  * the per-target INTERFACE_INCLUDE_DIRECTORIES generator expression that is
+    joined into -I flags on the g-ir-scanner command line.
+
+Filtering only the first path is not enough: JavaScriptCore-4.1.gir happens to
+have no bare /usr/include on its target, but WebKit2/WebKitGTK does, so the
+WebKitGTK introspection still failed via the generator-expression path. Filter
+both.
+
