* fix: handle various problems with bazaar service

Should fix cases where Bazaar was too slow to startup and had to be
killed in order to be used:

Fixes:
- bazaar-org/bazaar#1005
- ublue-os/bluefin-lts#928

Maybe even:
- ublue-os/aurora#1523

* don't need this

* fix: silence output of flatpak info
