Merge r479404 from www/nginx.

<Commitlog>

Some modules depend on other being there before.

For example, devel_kit needs to be there before a few other, so this
fixes, and allow for future fixes of this kind of problem:

configuring additional dynamic modules
adding module in /wrkdirs/usr/ports/www/nginx-full/work/array-var-nginx-module-0.05
error: ngx_devel_kit is required to build ngx_array_var; please put it before ngx_array_var.
