db67fcbe88 examples: add public key authentication to ssh_server_fork 
I noticed that there was no example showing server side public key encryption in the examples
so I added this one. I used authorizedkeys as a global to minimize the changes to the original
code as well as I was not sure the correct methodology of determining the .ssh directory location
for a user not using Linux. One code using the user parameter to determine the location to use
instead if desired.

531b80a60b kex: List also the SHA2 extension when ordering hostkey algorithms 
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.

If the server had an RSA host key, it provided unconditionally SHA2
signatures without consulting the client proposed list of supported host
keys.

This commit implements more fine-grained detection of the extension
to provide the client with valid signatures according to RFC 8332
Section 3.1.
