Avoid timeout in capture-system-logs due to df command

Code Issues Proposed changes

The `df` command can stall indefinitely on stale NFS mounts,
causing the playbook to time out. This leads to the entire job
failing with POST_FAILURE status, discarding controller logs
and impacting troubleshooting.
This patch changes `capture-system-logs` to run `df` with a 60s
timeout to prevent hangs from stale NFS mounts. If 'df' times out,
the mount output may help debug which NFS share is unresponsive.
