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.
