Ayke van Laethem d845f1e1b2 wasm: fix functions exported through //export
When a function is exported using //export, but also had a
//go:wasm-module pragma, the //export name was ignored. The
//go:wasm-module doesn't actually do anything besides breaking the
export (exported functions don't have a module name).

I've refactored and cleaned up the code, and in the process removed this
weird edge case.
