Remove misleading `ssh-dsa`
Remove misleading `ssh-dsa`

The keytype field is actually `ssh-dss` for DSA keys and they will not
be stored as `id_rsa.pub`.

Note that newer version of ssh actually also support
`ecdsa-sha2-nistp256` and others so it is also misleading to assume the
field always starts with `ssh-`.
