unify test names: EESSI_ + software name (with '-' replaced by '_') + optional label for type of test

[boegel]

As far as I can tell, there's no way to tweak the test name, it's always determined by the Python class name (see https://reframe-hpc.readthedocs.io/en/stable/manpage.html#test-naming-scheme)

Before these changes (with EESSI pilot 2021.12 as available modules):
