update for nfs-utils

This update fixes the following non-security issues with nfs-utils:

- nfsserver.init: another typo in --nfs-version 4. (bnc#849476)
- nfs-utils.spec: Require keyutils for proper idmap lookup.
- nfs.init, nfsserver.init: mkdir /run/nfs before trying to create a file
in there (bnc#859221)
- nfs.init, nfsserver.init: add X-Systemd-RemainAfterExit: true to ensure
services aren't shutdown if sm-notify reports an error (bnc#849387)
