module: Invalidate signatures on force-loaded modules

Orabug: 25308135

[ Upstream commit bca014caaa6130e57f69b5bf527967aa8ee70fdd ]

Signing a module should only make it trusted by the specific kernel it
was built for, not anything else.  Loading a signed module meant for a
kernel with a different ABI could have interesting effects.
Therefore, treat all signatures as invalid when a module is
force-loaded.
