vpd-tool:Option to fixSystemVPD keywords

This commit has an added option in vpd-tool that fixes system VPD
restorable keywords in an interactive way.
This option is required in a field usecase.

In the field when there is a fault in BMC and BMC gets replaced,
the replaced BMC VPD will now have all blank data. Now the Product
engineer can use vpd-tool fixSystemVPD option to update the BMC
critical keywords by chosing the corresponding keyword data from
system backplane.

Similarly when the system backplane is replaced,
using the option, the PEs' can copy the keyword data from BMC.

When both system backplane and BMC are replaced, the PEs' will have
option to update new value on both.

This interactive tool option eases keyword data updation and avoids
manual updation for each and every mismatching critical keyword.

Test: Tested on everest
