Don't include the module in protocol conformance manglings.

The cost of hacks to swift_conformsToProtocol is starting to outweigh any benefit to being principled here. We'll get a linker error now if multiple modules declare a conformance for the same type to the same protocol, but that's arguably a good thing for 1.0 anyway, since we aren't set up to get that right in other ways.
