By default, the list of already stored known host types is preferred,
but this selection so far ignored the SHA2 extension and excluded these
keys in the KEXINIT list leading to not using this extension if not
explicitly enabled from configuration.
This commit extends the default list with the SHA2 signatures algoritms
and compares only base types so they can be listed in the KEXINIT list.
This adjust the tests to expect the full list of algorithms to pass.
