Replace the upstream-recommended postStart hook, which runs
concurrently with the entrypoint and loses the race (observed: it
deleted the ip rule the restarted gluetun had just created, leaving the
container in a permanent CrashLoop behind the kill switch). A command
wrapper now removes stale table-51820 rules and the leftover tun
device deterministically before exec'ing /gluetun-entrypoint, covering
container restarts after unclean exits.
