[igt-dev] [PATCH i-g-t 1/2] runner/resultgen: relax results processing

[Kamil Konieczny]

We observed problems with resume runs when one of tests from
run fail to respond to SIGKILL and then don't exits, which
was reported like:

[1415.815247] Child refuses to die, tainted 0x40. Aborting.

After machine was rebooted runs were resumed but at the end
results from run wasn't processed due to error at comms file
from failed test. Try to correct that behaviour and count
results if at least one of files (comms or log) or dmesg was
successfully processed and fail only when both fail. Also
print more detailed info about what failed.
