nginx: change luci dependency and fix luci nossl

Luci nginx config file for non ssl varian had user as nobody nogroup. This cause some problem with ubus use.
Luci file support package depends on uwsgi-cgi. As this package will be renamed shortly to a more generic version, make the subpackage depends on the uwsgi subpackage only.
