Fix build error

WARNING: this fix is INCOMPLETE!; only the build error is fixed.

e1d13c9884e6f4579b1265400b61a36207748dc3 refactored SignalClusterView
into StatusBarSignalPolicy. SignalClusterView.java hasn't been removed
yet but is not used at all. Therefore, any Qualcomm modification to
SignalClusterView is lost in StatusBarSignalPolicy. Migrating the change
wasn't trivial due to the structural differences in between
SignalClusterView and StatusBarSignalPolicy. This migration can be best
done by the original author of the Qualcomm change.
