meson: Only rebuild when files checked in git change

Browse source 
This allows for faster rebuild avoiding to run the target when nothing
changed.

This approach is not ideal as we should find a way to actually know when
to rebuild based on information from cargo itself but there seem to be
no way to do it at this point.
