Subject: [PATCH] nscd: allow using systemd-userdb

If systemd-userdb is used to configure some users, nscd needs to read
the userdb files.

See also https://www.freedesktop.org/software/systemd/man/nss-systemd.html
for the list of possible filenames (and symlinks).

Fixes: http://bugzilla.opensuse.org/show_bug.cgi?id=1207698
