It would be more convenient to just have the `all` test group/alias, so that we can do `make test TEST=all`. This also gives a parallelism / run time benefit, as we do not wait for tests in each tier to complete before moving to next tier.

For some environments one also needs to supply a few keywords like `!printer` to skip tests that cannot complete without failure due to misconfiguration. I left the keywords as is to show how would a failing run look. There is also an existing shortcut in build system that allows to run this with `make test-all`.

I have nothing against it, but I don't think I know enough about details of jtreg configuration to provide approval. OTOH, I personally don't see a strong need for it.
