stand/zfs: Remove read-compatible features

Browse source 
These features are marked as ZFEATURE_FLAG_READONLY_COMPAT and so
irrelevant for read-only pool imports by the loader:

	"com.datto:resilver_defer",
	"com.delphix:obsolete_counts",
	"com.delphix:spacemap_histogram",
	"com.delphix:zpool_checkpoint",
	"com.intel:allocation_classes",
	"org.zfsonlinux:allocation_classes"

This should cause no functional changes, just a code cleanup.
