www-nginx/njs: new package, add 0.9.4

njs[1] is a "subset of JavaScript language to use in NGINX".

The primary dependency is dev-libs/quickjs-ng. The package consists of
roughly two parts: libnjs (including libqjs), and the actual njs_module.
libnjs is configured and built first in order to use the correct ar and
explicitly control other options (e.g. dependencies like OpenSSL, zlib
etc).
