Currently the software-controller-init.sh script may append
the config 'gpg-verify=false' to the end of the current feed
and sysroot ostree 'config' files everytime the host reboots.
This commit fix the issue by allowing the script to append the
config only if it does not exist.
Test Plan
PASS: AIO-DX - major release deployment stx8 -> stx10
PASS: verify the feed and sysroot ostree config files
