treewide: assume getline exists

Apparently, getline is being used unconditionally in pam_namespace and
pam_sepermit.  In pam_namespace, it is being used since 2006 when the
module was introduced in the first place.

Let's assume getline is universally available and let's use it
unconditionally in other cases, too.

* configure.ac (AC_CHECK_FUNCS): Remove getline and getdelim.
* libpam/pam_modutil_searchkey.c (pam_modutil_search_key): Use getline
unconditionally.
* modules/pam_pwhistory/opasswd.c (check_old_pass, save_old_pass):
Likewise.
* modules/pam_shells/pam_shells.c (perform_check): Likewise.
