Don't recommend indicator-sync

[Jeremy Bícha]

ubuntuone-client recommends indicator-sync. This should either be dropped to a suggests or dropped. It's generally not a good idea for a library to depend on (or recommend) a particular front-end implementation.

The dependency is unnecessary as unity already recommends indicator-sync.

GNOME Shell doesn't use indicators. Ubuntu GNOME includes the Ubuntu One libraries but not ubuntuone-control-panel-qt by default.
