Let zpool import ignore a missing hostid record.

Browse Source 
Change the zpool program to skip its hostid mismatch check in the
same way that libzfs already does.

Invoked imports fail if the ZPOOL_CONFIG_HOSTID nvpair is missing in
the /etc/zfs/zpool.cache file, which can happen as of the /etc/hostid
deprecation in commit zfsonlinux/spl@acf0ade362.
