Vincent Ambo e1e1764e32 feat(nix/buildTypedGo): Add a //nix/buildGo wrapper for typed Go
These functions work like buildGo.program & buildGo.package, but run
the .go2 sources through go2go first before passing them to the
//nix/buildGo equivalents.

# A crude wrapper around //nix/buildGo that supports the Go 2 alpha.
#
# The way the alpha is implemented is via a transpiler from typed to
# untyped Go.
