mesa: Fix build with wayland and egl

When wayland and egl both are on then it enables the wayland
plugin which actually fails to build because its not finding wayland-protocol
xml templates in proper location which is recipe sysroot since
we are cross compiling

Fixes build errors e.g.
make[4]: *** No rule to make target `//usr/share/wayland-protocols/unstable/linux-dmabuf/linux-dmabuf-unstable-v1.xml', needed by `drivers/dri2/linux-dmabuf-unstable-v1-client-protocol.h'.  Stop.
make[4]: *** Waiting for unfinished jobs....

+use PKG_CHECK_VAR for defining WAYLAND_PROTOCOLS_DATADIR
+
+This allows to override the wayland-protocols pkgdatadir with the
+WAYLAND_PROTOCOLS_DATADIR from environment.
+
+pkgconfig would return an absolute path in /usr/share/wayland-protocols
+for the pkgdatadir value, which is not suitable for cross-compiling.
