sign_gsc_firmware: drop version number check for node locked images
sign_gsc_firmware: drop version number check for node locked images

With introduction of Ti50 images the version of the eraseflashinfo
capable images must change, which will prevent signing scripts from
accepting Ti50 images from node locked signing.

Enforcing the version number is proving to be a larger pain that in is
worth: we do need to modify the version once in a while, and it takes
a lot of effort and time to propagate the version adjustment through
signing stages.

We already have a quorum requirement for eraseflashinfo capable node
locked images, this provides enough guarantee from accidental signing
or malicious signing of such an image, version number enforcement does
not add security.
