url: fix unix-socket support for proxy-disabled builds

Prior to this change if curl was built with Unix Socket support
(--enable-unix-sockets) and without Proxy support (--disable-proxy) then
unix socket options would erroneously be ignored.

Regression introduced in:
0b8d682f81ee9acb763dd4c9ad805fe08d1227c0

Bug: https://github.com/curl/curl/issues/1274

Closes https://github.com/curl/curl/pull/1289
