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`.

Okay - change is harmless with no ongoing maintenance cost.

Why no `jdk_all` definition in this case?
