    [test] Abort testing immediately on interrupt and sigterm · 4a2d9b1b

    This is a partial revert of:
    https://crrev.com/c/890938 and https://crrev.com/c/893982
    
    Before this CL, the test runner blocked on ongoing tests in order to
    process their results after an internal timeout. However, the logic
    required for this feature was overly complicated and prevented an
    acceptable implementation for fast aborts. Furthermore, also the fuzzers
    suffered from timeouts on swarming due to hanging tests.
    
    Instead, we now abort immediately on internal timeout (used on
    fuzzers), SIGINT (Ctrl-C) and SIGTERM. Ongoing tests are immediately
    terminated and their results are disregarded. On SIGTERM and SIGINT,
    we return with non-zero exit codes, and zero on internal timeout.
    
    This will also properly return json output, when the external hard
    timeout is reached on swarming (causes SIGTERM).
