Initial commit

PKGBUILD copied from truffleruby with slight tweaks (different GitHub
organization, no docs/ directory).

Similar to Ruby, launching graalpython with --polyglot doesn’t work, but
accessing Python from R works. For example:

    eval.polyglot('python','[i for i in range(1,20) if i%2 is 0]')
