prosodyctl: Allow install plugin via explicit path or URL

This way you don't need to set the server URL in the config to use this,
you could just ^C^V an install line from a web page that says

	prosodyctl install https://modules.example.com/mod_example.src.rock

Drop the help message in this case since it'll be all messed up by being
given an URL or rock filename.
