python3-cryptography: use python3-unittest-automake-output

Instead of using sed to reformat the output use this new module.

This shows that the previous sed expression wasn't sufficient because it
didn't handle tests throwing an error, and now the bench/ tests fail
because we don't have pytest-benchmark.  These tests are more of a
benchmark than a unit test, so just skip them.

Also show a skip message instead of nothing if the tests were skipped
due to a lack of memory.
