kselftest/alsa: Provide more meaningful names for tests

Rather than just numbering the tests try to provide semi descriptive names
for what the tests are trying to cover. This also has the advantage of
meaning we can add more tests without having to keep the list of tests
ordered by existing number which should make it easier to understand what
we're testing and why.
