x/crypto/ssh/agent: Fix keyring removing the wrong key(s)
The Remove method for the keyring sliced the internal keys list
incorrectly when removing a key. This caused the wrong key to be removed
or sometimes multiple keys were removed. Additionally, if the key to be
removed was the last key, the method never returned.
Fixes golang/go#13628
