Male Fitness Modifier Neck Fix

This is an override mod that fixes some weird areas around the neck caused by the male fitness modifier.

Due something I'm still trying to work around this Mod break some penis meshes.

This is because limitations of the software I used to create this fix.
If you don't use penis meshes that are affected by the sim's thighs shape, you can probably continue using this mod without noticing anything weird.

Simdulgence's penis meshes are unaffected.
