temp/mutter-mobile: force update of libmutter_api_version

The forked version includes some new API, but the maintainer wants to have things as-close-as-possible to upstream. Since APK mostly keeps track of libraries versions, having the same API version as upstream (there's no stable ABI for mutter), makes it possible for APK to confuse with non-mobile mutter. By having an unrealistic API version, we make sure this does not happen to us.

Fixes #2127 (closed)

Also patch the version in gnome-shell-mobile, so they stay in-sync.

This is untested, but I believe is the right approach. @u8l can you please give this a try? You can use https://wiki.postmarketos.org/wiki/Mrtest
