Remove useless check - ki_loginclass is an array; can't be NULL.

MFC r254134:

Add -c flag to pgrep(1) and pkill(1), to match login classes.

- Implement -q option for pgrep(1).

Initialize the execfile argument to NULL instead of _PATH_DEVNULL. This allows the -M option to be used without specifying -N.
