directfb: don't patch pkg-config files

We are currently getting build failures of projects that rely on
being able to access DirectFB's internal include directories, as
returned via pkg-config, since the include paths returned by
pkg-config are incomplete.

The reason for that is the patch that is being removed with this
change. It modified the cflags returned by pkg-config in an
incorrect way, causing us to miss important include paths:

For reference, pkg-config output with incorrect patch applied:
  ad@bril0118 #513 ~> pkg-config --cflags directfb-internal
-D_GNU_SOURCE -D_REENTRANT -I<builddir>/tmp/sysroots/<machine>/usr/include/directfb -I<builddir>/tmp/sysroots/<machine>/usr/include

Now, with the incorrect patch removed, the output is as expected:
  ad@bril0118 #514 ~> pkg-config --cflags directfb-internal
-D_GNU_SOURCE -D_REENTRANT -I<builddir>/tmp/sysroots/<machine>/usr/include/directfb-internal -I<builddir>/tmp/sysroots/<machine>/usr/include/directfb

Overall, the removed patch is not needed - pkg-config does the right
thing these days and we can simply use the correctly working upstream
versions of all DirectFB .pc files.
