gtk+3: remove redundant Wayland patch

The installation path and wayland-scanner location problems in Wayland were
resolved in "wayland: Fix installation patch issue" (oe-core 14c0d99) which made
the WAYLAND_PROTOCOLS_SYSROOT_DIR workaround redundant.

-Subject: [PATCH 4/4] configure.ac: Fix wayland-protocols path
-
-The wayland-protocols directory is used during build: Fix the path
-to point to sysroot specified in recipe.
-
-Normally PKG_CONFIG_SYSROOT_DIR could be used in configure.ac but that
-breaks multilib gtk+ as it would point to multilib sysroot when the
-(allarch) wayland-protocols is actually in the machine sysroot.
