[xfstests PATCH v2 3/3] tests: fix some tests for systems with fs.verity.require_signatures=1

[Eric Biggers <ebiggers@kernel.org>]

From: Eric Biggers <ebiggers@google.com>

Some of the newer verity tests don't work properly on systems where
fs.verity.require_signatures is enabled, either because they forget to
disable it at the beginning of the test, or they forget to re-enable it
afterwards, or both.  Fix this.
