respawn.sh: Add logging and limit loop iterations
Since we'll now log the script and its children output to a file, let's
make sure the loop doesn't run countless times upon failing child
process, producing lots of potential undesired output. For instance, if
osmo-bts fails to read vty config and exits immediately.
