Compile wifi-service against framework-wifi.impl

Previously, "framework-wifi" was the implementation library. Switching
to java_sdk_library means that references to "framework-wifi" will
usually be resolved to the stubs. This change explicitly depends on
the implementation. This is safe to do because the "wifi-service" and
"framework-wifi" are in the same APEX.
