Thanks Andrey!  One thing that you overlooked is that _fsv_have_hash_algorithm()
needs to restore the previous value of fs.verity.require_signatures, not the
value that existed at the beginning of the test.

Also, I found that some of the newer tests don't work properly on systems where
fs.verity.require_signatures=1.  I'd like to fix that too.

Can you take a look at the patchset
https://lore.kernel.org/fstests/20221104064742.167326-1-ebiggers@xxxxxxxxxx/T/#u
I just sent out?  It should take care of everything...
