5159cd96e8 knownhosts: Make sure we have both knownhosts files ready 
If either one is missing at this point, fill it with default vaules in
ssh_options_apply().

Previously, when setting up only knownhosts, global_knownhosts file
was left pointing to NULL and the ssh_known_hosts_read_entries()
was trying to open NULL file which is invalid.

893b69d82b knownhosts: Use the correct name for ECDSA keys for host key negotiation 
The conversion from  ssh_keytype_e  to string does not work for ECDSA keys,
because different key lengths have different string representation.

The usage of  type_c  should work also for every other key type in future,
but it does not reflrect different signature types (SHA2 extension for RSA
keys), but this early in the key exchange phase, we can not make any
assumptions about supported extensions by the server.
