Create the NV seed file for the tests if needed
Write an all-bits-zero NV seed file for the tests. Without this, if
the seed file is not present when this test suite is executed, the
PSA module initialization will fail, causing most test cases to fail.
Also write an all-bits-zero NV seed file at the end. The test cases in
this test suite mess with the file, but subsequent test suites may
need it.
