Expllicitly skip API tests for compatiblity tests on 2.7 and 2.8

The Providers[fab] tests are generally excluded when backwards
compatibility tests for 2.7 and 2.8 are run, however in some situation
when selective checks determine that API tests should be run as well
(for example when FAB code is modified), the FAB tests are also
added to list of test types.

This PR explicitly skips the whole TEST_TYPE execution in case
Airfow 2.7 or 2.8 are supposed to be installed when running the tests.
