resurrect lang/haxe with pre-packaged opam root

[Thomas Frohwein]

Hi,

When we last had lang/haxe in ports, it was broken because of fetching
online OPAM packages during the build until we removed it. I wanted to
take a shot at resurrecting it. This is the latest release 4.3.6 and
the OCaml dependencies are now in a tarball of a locally created OPAM
root directory. This way no internet connection is needed during the
build. A convenience target `make opamroot-helper` can help with future
updates.

chrisz@, I would appreciate a look at this approach to handling OPAM
dependencies during the build.

This builds now and I can run the basic hello world program as expected.

I am also including an update to lang/nekovm to 2.4.0 that is what Haxe
4.3.6 expects. It's not used by anything else in ports FWIW. Re-import
of haxe would of course require adjustment to devel/quirks.

ok? comments?
