dbus-sdr: write-back to fruCache upon modification

ipmiStorageWriteFruData is a read-modify-write cycle:
1) Obtain a copy of the target FRU with getFru()
2) Modify the copy
3) Write modified copy FRU to EEPROM by calling `writeFru(fru)`
   or `writeFru(fruCache)`.

For 3) above, whether `writeFru(fru)` or `writeFru(fruCache)` is
called depends on the value of `atEnd`.
Currently fruCacue is not updated in the atEnd==false branch, where
`writeFru(fruCache)` is called. This may cause the unmodified FRU
content to be written back, as if the write did not happen.
This change adds the write-back operation.

Tested: FRU write works
