sysprof: Upgrade to git version slightly past 3.20

New version uses Gtk+3. 3.20 release requires a bunch of fixes to
build without polkit, this git revision inclues those fixes.

* Add patch to use proper U64_TO_POINTER macro to fix build on
  32 bit platforms.
* Forward port memory barrier patches for arm & mips
* sysprof builds with loads of warnings and git builds also use
  -Werror: avoid that by setting "--enable-compile-warnings"
