image_signing: Remove legacy unified build feature

This feature was originally implemented before go/cros-unibuild-signing.
It only provided basis support to continue testing unibuilds, but didn't
deal with the actual required model specific cases.

Unibuilds have already been migrated away from this, so this feature is
now obsolete.
