Rename Binder.destroy() to Binder.destroyBinder().

There are a few AIDL-generated stubs that perform "destroy"
transactions and call "this.destroy()". Previously, this
resolved to the "destroy()" method from their interface on
ART while resolving to Binder.destroy() on the RI, though
this is a subject of a bug report against the JDK,
    http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8021581 .
Resolving to the private Binder.destroy, inaccessible to
the Stub, would lead to throwing IllegalAccessErrror.

As we're changing the method lookup to be closer to RI, see
    https://android-review.googlesource.com/413119 ,
we should stay clear of the problematic cases whether we
make a decision to follow the RI precisely or not. Therefore
we rename the Binder.destroy() to Binder.destroyBinder().

Test: Nexus 6P boots.
