Fix for sensor value PATCH in manufacturing mode

Issue: Not able to PATCH sensor value in manufacturing mode, as
manufacturing mode is not getting updated after BMC reboot.

Added support to cache initial value of `SpecialMode` property on
startup and register for `InterfacesAdded` signal in case
`specialmodemgr` service starts late.

Tested:
1. Verified `manufacturingMode` value is getting updated as expected.
Verified the same over different scenarios like service(specialmodemgr,
hwmontempsensor, cpusensor) restart and `SpecialMode` property update.
2. Verified PATCH operation is working as expected over BMC resets
in manufacturing mode.
