Witherspoon: Enable PNOR signature verification

Enable signature verification in the openpower-software-manager code
for witherspoon. This causes an error to be logged if updating to
an unsigned image, or image signed with a different key than the one
on the system, and if field mode is set, it'll stop the activation
process.

Tested: PNOR signature verification is enforced on witherspoon,
verified error is logged with and without field mode enabled, and
activation is prevented with field mode enabled.
