Fix indent in git-fs code in initrd
Silence git-fs related message in initrd
Move mounting /.git into live-config.sh

Previously, this happened in initramfs, since it needed to change mount
options. However:
 - now git-fs is always mounted with noforget
 - aufs can be easily remounted to disable noxino
so mounting /.git no longer needs to happen in initramfs. As an added
advantage, this means /.git is also available when debugging is enabled
through the config service instead of the actual kernel cmdline.

Closes: #115
Update initramfs
