samba-data-tool option refuses to take its optional argument

I noticed this while debugging a problem on my system.

The --samba-data-tool option should take a required argument, but instead it complains:

[root@scooter ghartzell]# adcli update --add-samba-data --samba-data-tool=/bin/net
update: option '--samba-data-tool' doesn't allow an argument
usage: adcli update

  -D, --domain=<...>        active directory domain name

  --show-details            show information about joining the domain after
                            a successful join

                            successful join
  --add-samba-data          add domain SID and computer account password
                            to the Samba specific configuration database
  --samba-data-tool         Absolute path to the tool used for add-samba-data
  -v, --verbose             show verbose progress and failure messages

The problem is almost certainly right here in computer.c, where instead of no_argument is should read required_argument.

I'm not set up to build adcli. I could PR the change but have no simple way to test it....
