compiler/natives/src/runtime: Add stubs for getcallerpc, findfunc, funcname.

These are used by the new panicwrap implementation. panicwrap wasn't implemented previously either, so this is not a regression. Related to golang/go@354fa9a. Fixes: runtime/error.go:134:8: undeclared name: getcallerpc runtime/error.go:135:10: undeclared name: funcname runtime/error.go:135:19: undeclared name: findfunc
