Sync keyword update to inherited FRUs

This commit syncs keyword update to all inherited FRUs.
When a keyword value is updated either from vpd-tool or from vpd-manager
WriteKeyword API, the keyword update should also be synced to all
inherited FRUs on PIM to prevent mismatch.

Test:
```
Tested on a rainier 2s2u simics setup.

1. Ensure BMC is in Ready state
2. Read VINI PN of /system/chassis/motherboard using vpd-tool
3. Update VINI PN of /system/chassis/motherboard using vpd-tool
4. Once vpd-tool returns success, read VINI PN of inherited FRUs
   /system/chassis and /system/chassis/motherboard/tod_battery
5. VINI PN value should be same on the inherited FRUs.
```
