ZTS: Another round of changes for FreeBSD

Highlights:
* is_linux -> is_illumos swaps
* make block_device_wait more clever when paths are given
* slightly optimize default_cleanup_noexit
* remove platform differences in user_run
* temporarily expect non-libfetch behavior for keylocation=/foo/bar
* fix sharenfs exceptions
* don't test multihost property
* fix misc broken platform checks
* clear zinjected faults in removal_resume_export callback
