archlinux sync: no MIME magic files found

[SantiagoTorres]

Trying out a rebuilderd worker for arch, the sync service fails with:

Nov 24 21:19:31 localhost systemd[1]: Started rebuilderctl sync: periodically import packages.

This makes me wonder whether tree_magic_mini is looking for some sort of xdg-mime database that's not populated...

hi!

It's looking for a file from the shared-mime-info package that was missing in the Dockerfile, this should be fixed after #92.

Thanks for reporting this!
