Subject: [PATCH] Add compatibility file sets (ZoL 0.6.1, 0.6.4, OpenZFS 2.1)

ZoL 0.6.1 introduced feature flags with the three features that all
implementations at the time were guaranteed to have.  0.6.4 introduced
a few more until 0.6.5 added two after that.  OpenZFS 2.1 added the
dRAID feature.

Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov>
Signed-off-by: Mike Swanson <mikeonthecomputer@gmail.com>
Closes #11818
