kex: Honor more host key algorithms than the first one (ssh-ed25519)
The code as it was written used only the first algorithm from preferred_hostkeys array and compared it with the list returned from the known hosts. This commit is fixing the code so we actually compare each of the algorithms from both of the lists and returns the intersection.
