mon: register tell/asock commands using info from local_mon_commands

since all tell/asock commands are listed in local_mon_command, and all
of them are noforward, also all noforward commands are tell/asock
commands. we can just use the information from local_mon_command to
register them, to avoid the repeating, and for better readability.
