[roll pigweed] Revert "pw_unit_test: Cleanup test processes properly on timeout"

This reverts commit 963e9bd4d97ba227c4283090b58b8b706eceff5d.

Reason for revert: Breaks failing tests

Original change's description:
> pw_unit_test: Cleanup test processes properly on timeout
> When processes launched were killed due to timeout, their child
> processes were orphaned and left running. Add a trap to the test runner
> script to cleanup the test processes when terminated. Switch to using
> SIGTERM instead of SIGKILL to allow the script to catch and handle it.
