compiler/gopherjspkg: Add package.
This package embeds the core GopherJS packages (js, nosync). It's similar to how native overrides for stdlib are embedded in the compiler/natives package. Pick only files in /fs and /nosync, and no subdirectories (if any are added, they won't get included by default).
