Add "ruser" and "luser" options. The former corresponds to the current
behavior, where the module checks that the supplicant is a member of the
required group. The latter checks the target user instead. If neither
option was specified, pam_group(8) assumes "ruser" and issues a warning.
I intend to eventually change the default to "luser" to match the
behavior of similarly-named service modules in other operating systems.

Makefile and man page which I'd forgotten to 'cvs add'.
