[systemd-generator]: Fix dependency update for multi-asic platform (#4820)

Browse Source 
* [systemd-generator]: Fix the code to make sure that dependencies
of host services are generated correctly for multi-asic platforms.
Add code to make sure that systemd timer files are also modified
to add the correct service dependency for multi-asic platforms.

Signed-off-by: SuvarnaMeenakshi <sumeenak@microsoft.com>

* [systemd-generator]: Minor fix, remove debug code and
remove unused variable.
