tests: store msgtest in -q mode for display in msgfail

Not-quiet output is very verbose and with our growing array of tests
generates many many lines which e.g. kills the log display in travis-ci
and obscures failures and uncatched output in a wall of details.

The -q mode fixed this by callapsing passed tests to a single P and now
with some rework we can even get failures properly displayed with the
message from msgtest.
