units: add 'SmackFileSystemRoot=*' option into tmp.mount

If SMACK is enabled, 'smackfsroot=*' option should be specified when
/tmp is mounted since many non-root processes use /tmp for temporary
usage. If not, /tmp is labeled as '_' and smack denial occurs when
writing.

In order to do that, 'SmackFileSystemRoot=*' is newly added into
tmp.mount.
