Linux xargs calls the command with no arguments if it gets no inputs, which
`docker rmi` complains about. It provides -r / --no-run-if-empty to prevent
this but unfortunately this isn't supported on OSX.
Ignore errors from `docker rmi` so that `make clean` will keep going and clean
up later stuff.

The client on the host may time-out the connection attempt after we have
accepted it. If the mount fails, sleep for 1s and try again.

The database has a reconnect loop, and we don't particularly want
to accept more than one of its connections per mount.
