Subject: [PATCH] configure.ac: fix build failure when crypt() does not require
libcrypt
Since commit 522246d20e4cd92fadc2d760228cb7e78cbeb4c5, the build fails
if "none required" is returned by AC_SEARCH_LIBS for libcrypt.
Resolves: https://github.com/linux-pam/linux-pam/pull/235
Fixes: http://autobuild.buildroot.org/results/92b3dd7c984d2b843ac9aacacd69eec99f28743e
Fixes: v1.4.0~228 ("Use cached 'crypt' library result correctly")

pam_modutil_check_user_in_passwd and use it in pam_faillock.c instead of
fgetpwent_r which is not available on musl
