libcommuni: Renamed from communi

The communi repository have been renamed to libcommuni.
libcommuni: Update configure patch

Previous patch was partially merged upstream (only the Autoconf part),
so we move GNOME Build API support here.
ostree-triggers, ostree: Track an older version

Since bb6eedfb258d3001f61c42c7e920c03dae2bdc1a, OSTree has a new
deployment method which requires a lot of changes, but we are not
yet ready, so we track the previous revision.
Rename maui-ostree-integration and maui-ostree-live-integration

The maui prefix is useless, rename it to make it consistent with
the installer component.
