libpam: Backport ptest fix checking whether files exist

Backport a patch to check whether files exist.

Before the patch:
 # ./run-xtests.sh . tst-pam_access1
 mv: cannot stat '/etc/security/opasswd': No such file or directory
 PASS: tst-pam_access1
 mv: cannot stat '/etc/security/opasswd-pam-xtests': No such file or directory
 ==================
 1 tests passed
 0 tests not run
 ==================

After the patch:
 # ./run-xtests.sh . tst-pam_access1
 PASS: tst-pam_access1
 ==================
 1 tests passed
 0 tests not run
 ==================
