Colin Percival ca82268b2a Silence warning printed by getfsspec(3) when /etc/fstab does not exist
fstab: /etc/fstab:0: No such file or directory
and from dump(8) when setfsent(3) fails due to /etc/fstab not existing:
  DUMP: Can't open /etc/fstab for dump table information: No such...

This makes daily and security periodic runs somewhat cleaner in jails
which lack /etc/fstab files.
