runner: Avoid null characters in results.json

CI pipeline (namely, cibuglog) doesn't cope well with strings that
have \0 in them. If null characters appear in output files, pretend
the output stops at the first such character. Well behaving tests
should not print them anyway.

The case in CI happened due to some hang/crash/explosion/solar flare
that corrupted the output of a test.
