include/opt: Emit an error message when an option is redefined

When the caller attempts to redefine an option, `opt_add_arg()` fails
without printing an error message, leaving the situation undetected
if the caller does not check the return value of the call.

This commit modifies `opt_add_arg()` to print an error message when
a caller attempts to redefine an option.
