[pbs-devel] [PATCH proxmox-backup] task tracking: improve pruning of reused-PID stale entries

[Hannes Laimer]

Keep entries only when check_process_running(pid) reports a
starttime equal to the stored one. This improves pruning of stale
entries for all PIDs (not just the current one) and aligns update
with the read path. Counting behavior and semantics are unchanged.

noticed while looking through recent proposed changes to the tracking
logic. this isn't a problem, but should keep the tracking file cleaner
and remove a match arm in the code
