Revert "ANDROID: vendor_hooks: Add hooks for binder proc transaction"

Browse Source 
This reverts commit cb7e10d31b.

The hook android_vh_binder_proc_transaction_finish is 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.
