zpool import -t should not update cachefile

Browse Source 
zpool import's -t parameter is intended for use with -R when operating
on pools that belong to other systems. Like -R, pools imported in this
way should not update the cachefile unless explicitly requested. The
initial implementation allowed the cachefile to be updated when -R was
not used. This went uncaught during testing because -R had implicitly
disabled use of the cachefile.
