It was previously reported[1] and discussed that tests booting full
blown distros and relying on TCG would take too much time to run,
especially in the environments given by GitLab CI's shared runners.

This is an implementation of a proposal to exclude those tests from
being run by default on `make check-avocado` invocations.  To make it
extra clear, all tests are still available, but those that are tagged
with "accel:tcg" and "boots:distro", are filtered out by default on
`make check-avocado`.

This is the situation of the Avocado GitLab CI jobs with and without
the changes in this PS:

Assuming the jobs run in parallel, the overall wait time for all the
Avocado jobs to complete is now ~12 minutes.
