Support receiving RFC 8332 rsa-sha2-* host keys.

Browse Source 
This is the cleanest part of the RFC 8332 support: I simply add two
more RSA-based SSH-2 key algorithm vtables, both almost identical to
the existing one, with different ssh_id strings and signature flags.

Adding those to the HOSTKEY_ALGORITHMS list macro is enough to ensure
that we advertise support for the new identifiers in our client
KEXINIT, select the appropriate algorithm if the server announces one
or both of them too, and use the right version of the signature
validation.
