cam: options: optional arguments needs to be specified as --foo=bar
It's not stated in the getopt_long documentation but optional arguments
need to be specified as '--foo=bar' instead of '--foo bar', otherwise
the value is not propagated to optarg during argument parsing. Update
the usage printing helper to reflect this requirement.
