[Toybox] bug: commands with no options silently allow all options

[enh]

commands with options are fine:

$ ./toybox df -z
...
df: Unknown option z

but any command with no options silently ignores any options:

$ ./toybox uptime -z
 10:07:34 up 34 days, 30 min,  6 users,  load average: 4.44, 2.28, 1.46
$ ./toybox uptime -z g
 10:08:26 up 34 days, 31 min,  6 users,  load average: 3.65, 2.46, 1.57
$ ./toybox uptime g
 10:08:28 up 34 days, 31 min,  6 users,  load average: 3.65, 2.46, 1.57
