ZTS: Misc fixes for FreeBSD

* Force UFS sync before snap in vol rollback tests
* rw is not a valid share option on FreeBSD, use ro instead
* zfs_unmount_nested: mountpoint is in the pool, rmdir *before* export
* Fix some more platform checks
* Fix disappearing group in delegate tests
* Don't try delegating for jailed, only root can set it
