This reverts commit acefa91e51.
The hooks trace_android_vh_binder_proc_transaction_entry and
trace_android_vh_binder_select_worklist_ilocked are not used by any
vendor, so remove it to help with merge issues with future LTS releases.
If this is needed by any real user, it can easily be reverted to add it
back and then the symbol should be added to the abi list at the same
time to prevent it from being removed again later.
