[PATCH 2/7] test-lib: add say_color_tap helper to emit TAP format

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Follow-up 5099b99d25 (test-lib: Adjust output to be valid TAP format,
2010-06-24) and make it easy to distinguishing when we're emitting TAP
directives (with the new "say_color_tap"), and when we just want to
say something with colored text "say_color".

This also makes it easier to do any follow-up changes where we'd like
to do something special with the TAP directives, as they're what
drives the test when we run under the prove(1) utility.
