[tools] testbot/LogUtils: Improve handling of child process crashes.

[Francois Gouget]

The "unhandled exception in child process" line also tells us the pid
of the child process so we can add it to the list of pids for the
current test unit.
ParseWineTestReport() should also count at least one failure for the
child process (in case the regular "unhandled exception" line got
lost).
