Ian Rogers c7dacfb87b tools subcmd: Robust fallback and existence checks for process reaping

Update check_if_command_finished() and wait_or_whine() to handle invalid
PIDs gracefully (<= 0) by setting cmd->finished = 1 and returning early.
This avoids executing waitpid(-1, ...) or waitpid(0, ...) downstream,
which can block or reap parallel tests' exit status causing state
corruption.

Introduce a fallback mechanism in check_if_command_finished() using
waitpid(..., WNOHANG) when /proc/<pid>/status is inaccessible (e.g. due
to EMFILE/ENFILE) to safely check and reap finished children.
