Add the zpool and filesystem versions

Print the supported zpool and filesystem versions at module load
time.  This change removes an ambiguity and adds information that
system administrators care about.  The phrase "ZFS pool version %s"
is the same as zpool upgrade -v so that the operator is familiar
with the message.

  ZFS: Loaded module v0.6.0, ZFS pool version 28, ZFS filesystem version 5
  ZFS: Unloaded module v0.6.0
