[client] Prevent corruption from competing log rotation and improve debug bundle (#6214)

Browse Source 
* Adds heuristic to detect an edge case on Linux where a system has configured logrotate as a separate service to rotate log files which would mangle our client log files. If we detect logrotate being configured for netbird, we disable our rotation.

* Adds new env var to disable log rotation: NB_LOG_DISABLE_ROTATION

* Adds compressed and plain logrotate files to debug bundle.

* Replaces lumberjack with timberjack (maintained fork with bug fixes and extra features).

* Clarifies which daemon version is running in the bundle stats.

* Change logging for client service status to console
