fix: test: temporarily exempt SynthPorep constants from test

Related Issues

TestSDRLayersDefined has been failing on master, it's new in #11011. This is because it tests over all SealProofInfos as defined in go-state-types, which includes synth porep stuff.

Proposed Changes

• Explicitly skip this check for the synth porep range for now
• We should remove this when feat/nv21 is merged into master (will open issue for it)
• The real solution is that we're gonna need to start having integration branches in go-state-types for stuff like this
