[PATCH v2] tests/acceptance: allow control over tags during check-acceptance

[Willian Rampazzo]

Although it is possible to run a specific test using the avocado
command-line, a user may want to use a specific tag while running the
``make check-acceptance`` during the development or debugging.

This allows using the AVOCADO_TAGS environment variable where the user
takes total control of which tests should run based on the tags defined.

This also makes the check-acceptance command flexible to restrict tests
based on tags while running on CI.

e.g.:

AVOCADO_TAGS="foo bar baz" make check-acceptance
