Edward Welbourne f20adcde30 Dodge qFatal() so as to get coverage results despite it
The silent and blacklisted selftests of testlib end in a qFatal(), to
test its messaging is handled correctly.  However, this prevents hooks
in main() from saving coverage data when we're gathering that.  So use
a transient signal handler that longjmp()s back to a setjmp() just
before the qFatal() to let the test complete normally (but, since
qFatal() does something different on MS-Win, don't apply this to it).

Note that testlib's internal FatalSignalHandler handles all fatal
signals *except* SIGABRT, so this isn't over-riding it.  (In any case,
this restores the prior signal handler in setjmp()'s catch branch.)

Added missing expected_silent.tap test output while checking that this
change doesn't affect (the rest of) the test output.
