Detect failing tests in parallel shard runner

Browse Source 
The previous logic considered a shard "passed" if its log contained any
[  PASSED  ] line, missing the case where some tests pass and some fail
(both [  PASSED  ] N tests. and [  FAILED  ] M tests, listed below:
appear in the gtest summary). Exit codes from the test binaries were
also ignored.

Now require both: an [  PASSED  ] line, no [  FAILED  ] line, and a
zero exit code. Track each shard's PID so wait can surface non-zero
exits.
