Handle ECC update

By default openpower-vpd-parser contains dummy code of ecc_create
which writes 0s to the vpd-ecc. And this corrupts the ECC.

This commit will not allow the user to update any record-kwd-data
with dummy ecc_create code as it returns -1. If want to update any vpd
data then build your image with vpdecc functions implementation.

Test-
when tried to update the keyword-
busctl call com.ibm.VPD.Manager /com/ibm/VPD/Manager com.ibm.VPD.Manager WriteKeyword ossay  "/system/chassis/motherboard" "VINI" "PN" 1 65
ERROR: ECC update failed

And another terminal output-
root@rainier:/tmp# ./vpd-manager
Error: Couldn't update the ECC
