    Testsuite: check actual_prof_file only when needed
    
    Might be a little faster. Avoids testing for #6113 (.prof file not
    written when process is killed with any signal but SIGINT) for tests
    that don't have a .prof.sample file (which is almost all of them) when
    running the profiling ways.
    Tests that were failing because of #6113: T8089, overflow1, overflow2 and
    overflow3.
    
    (cherry picked from commit e3b9dbf48c7b7b1ac4a5d6ecf1411469b5f7666c)
