www-nginx/ngx-lua-module: new package, add 0.10.27

This package requires two environmental variables being set in order to
use Lua: LUAJIT_LIB and LUAJIT_INC. The former is set to /usr/${libdir},
for the latter one, the ebuild uses pkg-config directly to get the
include directory.

+
+In Gentoo, NDK is a mandatory dependency. Make life easier for everybody
+and just define the NDK macro.

+Subject: [PATCH] Do not log error if non-OpenResty Lua is used
+
+Users are perfectly capable of reading the recommendation on README and
+deciding themselves which distribution of Lua to use. There is no need
+to scream at the users each time NGINX is started.
