AccessibilityServiceInfo does not report properly the feedback type.

Since the feedback type is an integer the bits of which correspond to a given
feedback type, the AccessibilityNodeInfo#feedbackTypeToString should return a
string representation of all feedback types. The current implementation
incorrectly assumes that the argument had only one flag set. Note that this
is a new ICS API and we would like to have this fixed.
