libpam: make /etc/passwd checks 8 bit clean
libpam/pam_modutil_check_user.c: explicitly convert the character read from /etc/passwd to type "char" to get the same signedness as the one compared with. Otherwise the functionality will depend on the (implementation defined) signedness of "char" on the platform built for.
