Subject: [PATCH] include/opt: Emit an error if a required parameter is missing

When an option expecting a parameter is not passed one, `opt_parse()`
does not fail because of an incorrect comparison.

This commit fixes the comparison so that `opt_parse()` fails and
prints an error message when a required parameter is missing.
