migrator: Customise startup sequence to fix #1673 (Thanks acidsys)
Diverge from util.startup.prosodyctl() in order to skip unneeded
behavior, such as loading the *Prosody* config file, which we do not
need here, based on the `--config` flag which should point at the
migrator config file instead.
Notably removed:
* read_config() since this loads the Prosody config
* check_unwriteable() which checks logfiles specified in the Prosody config, so not relevant
* make_dummy_hosts() but the migrator sets up its own hosts during migration
