devel/cgit: Fix builds in live environment, and add LUA option
- Remove adding of "openssl" directories to git subtree. openssl isn't necessary here, and the resultant include of "/usr/local/include" poisions the git tree, causing it to not compile.
- Add option to add the lua / luajit engine to the install.
- Reformat to satisfy portclippy and portfmt.
