mandos-keygen: Avoid comment lines from ssh-keyscan

In ssh-keyscan from OpenSSH 9.8, comment lines containing the hostname
and SSH protocol banner are emitted by to standard output.  Avoid this
by passing the "-q" (quiet) option to ssh-keyscan.

mandos-keygen: When scanning localhost for keys, try to run
"ssh-keyscan" both with and without the "-q" option.  If the "-q"
option worked, use the option also in the generated checker command.
