[PATCH] Allow to specify wayland-protocols datadir

[Marius Vlad]

This is particularly useful when cross-compiling and we need to specify a custom
datadir path for wayland-protocols. Cross-compilation toolchain is usually
immutable, and in this way we can modify wayland-protocols independently from
what the toolchain provides.
