[JENKINS-42959] Correctly compare key algorithms during key verification
[FIXED JENKINS-44046][FIXED JENKINS-43979] Use a larger default key size to fix issues when using SHA256 MACs during Diffe-Helman key exchange against older versions of OpenSSH

Fixes issues encountered following the recent move to the latest Trilead version. These fix 2 underlying issues:

    diffe-helman-sha256 Key Exchange needs at least 2048 bits of data to generate a key against OpenSSH 6.4 and below.
    Known hosts comparison incorrectly compares the hostname against the key value meaning key verification always fails when using known hosts files
