Revert "Dodge qFatal() so as to get coverage results despite it" 

This reverts commit f20adcde30. The
implementation had the right idea, but this is not expected to work
reliably in C++. It's jumping out of several frames without cleaning
them out properly and our ASan-based memory leak-checker has started
complaining (the next commit will move this test elsewhere).

   ==19313==ERROR: LeakSanitizer: detected memory leaks

 Direct leak of 258 byte(s) in 1 object(s) allocated from:

The restoration of the signal handler (which QtTest now has) is also
wrong: this needed to use sigaction() instead.
