x11-misc/xdg-user-dirs-gtk: EAPI 7, support cross-compiling

The build system prevented the CHOST pkg-config from being found,
so this specifies it as the cache variable to work around it.

It also wants to know the path of a runtime dependency, so that is
specified with EPREFIX so it isn't required at build time.
