Remove Lua support

Lua support is unused and the dlsym fwrite/write hacks horrify me.
Clean it up.

 can configure this location (and a few other things) by providing a `cgit.conf`
 file (see the Makefile for details).
 
-If you'd like to compile without Lua support, you may use:
-
-    $ make NO_LUA=1
-
-And if you'd like to specify a Lua implementation, you may use:
-
-    $ make LUA_PKGCONFIG=lua5.1
-
-If this is not specified, the Lua implementation will be auto-detected,
-preferring LuaJIT if many are present. Acceptable values are generally "lua",
-"luajit", "lua5.1", and "lua5.2".

-        Executes the script using a built-in Lua interpreter. The script is
-        loaded once per execution of cgit, and may be called multiple times
-        during cgit's lifetime, making it a good choice for repeated filters
-        such as the 'email filter'. It responds to three functions:
-
-        'filter_open(argument1, argument2, argument3, ...)'::
-                This is called upon activation of the filter for a particular
-                set of data.
-        'filter_write(buffer)'::
-                This is called whenever cgit writes data to the webpage.
-        'filter_close()'::
-                This is called when the current filtering operation is
-                completed. It must return an integer value. Usually 0
-                indicates success.
-
-        Additionally, cgit exposes to the Lua the following built-in functions:
-
-        'html(str)'::
-                Writes 'str' to the webpage.
-        'html_txt(str)'::
-                HTML escapes and writes 'str' to the webpage.
-        'html_attr(str)'::
-                HTML escapes for an attribute and writes "str' to the webpage.
-        'html_url_path(str)'::
-                URL escapes for a path and writes 'str' to the webpage.
-        'html_url_arg(str)'::
-                URL escapes for an argument and writes 'str' to the webpage.
-        'html_include(file)'::
