testsuite: Treat not tested as non failure and reduce verbosity

[rdmark]

Overhaul of testsuite to reduce default verbosity for more readable test logs, and treat NOT TESTED and SKIPPED as non-failure for more consistent results in a CI environment.

Restore a handful of tests that were made functional by recent code improvements.

Standardize on -v for medium verbosity and -V for high level of verbosity logging.

Refashion the -x (Exclude) option for flagging tests that are failing with Netatalk 4.0 for unknown reasons. Investigation required.

Colorize also the SKIPPED test results.

All of this results in a cleaner test log and test report generated by spectest.sh that is much more readable. Sample:
