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
It should have depended on mutter-mobile-schemas instead of
mutter-mobile. Looks like mutter-mobile-schemas was getting installed
instead of mutter-mobile for it only by chance until now.
