sync: make .git init more robust

Hitting Ctrl-C in the middle of this func will leave the .git in a
bad state that requires manual recovery.  The code tries to catch
all exceptions and recover by deleting the incomplete .git dir, but
it omits KeyboardInterrupt which Exception misses.

We could add that to the recovery path, but we can make this more
robust with a different approach: set up everything in .git.tmp/
and only move it to .git/ once we've fully initialized it.
