Meson: Override glib-compile-resources/schemas

This fix build error for projects that use gnome.compile_resources()
when glib is built as a subproject and not installed on the build
machine.

Note that this is not working for cross compilation cases, because it
would require to compile everything twice (for host and build machines).
A better solution would be to rewrite those tools in python. See #1859.
