mutter: fix profiler PACKAGECONFIG

In case "profiler" PACKAGECONFIG is enabled, the build fails with
the following error:

| ninja: error: '/usr/share/dbus-1/interfaces/org.gnome.Sysprof3.Profiler.xml', needed by 'src/meta-dbus-sysprof3-profiler.c', missing and no known rule to make it

meson.build script is looking explicitly for a required file using the
sysroot of the build system instead of ${RECIPE_SYSROOT}. To avoid this,
patch meson.build to prefix this path with ${RECIPE_SYSROOT}.

+Subject: [PATCH] Don't use system sysprof dbus folder
+
+In case Mutter is built with profiler support, it requires
+org.gnome.Sysprof3.Profiler.xml file to be available - however
+the meson build file is trying to access it on the build machine's
+system ($datadir/dbus-1/interfaces) instead of searching for it
+in the $RECIPE_SYSROOT.
+
+To ensure that it looks for this file in the correct folder, prefix
+the search path with the value of the sys_root property, which is set 
+in the meson.cross file (by meson.bbclass).
