policycoreutils: Improve error message when selabel_open fails

Browse Source 
When selabel_open fails to locate file_context files and
selabel_opt_path is not specified (e.g. when the policy type is
missconfigured in /etc/selinux/config), perror only prints
"No such file or directory".
This can be confusing in case of "restorecon" since it's
not apparent that the issue is in policy store.

Before:
  \# restorecon -v /tmp/foo.txt
  No such file or directory
After:
  \# restorecon -v /tmp/foo.txt
  /etc/selinux/yolo/contexts/files/file_contexts: No such file or directory
