[PATCH] builtin/fsmonitor--daemon: use parse-options API fully

["Carlo Marcelo Arenas Belón" <carenas@gmail.com>]

--help and -h are already handled internally so just parse_options()
do the parsing and extract the command from the remaining options.

as a side effect, avoid setting a variable argc to a value that was
never used.
