If the host only has RSA, use its RSA + generate ecdsa + ed25519, etc.
Perhaps fixes https://twitter.com/colek42c/status/1550554439299244032 and
something else that was reported.

While we rearrange/upstream things.
gliderlabs/ssh is forked into tempfork from our prior fork
at be8b7add40
x/crypto/ssh OTOH is forked at
https://github.com/tailscale/golang-x-crypto because it was gnarlier
to vendor with various internal packages, etc.
Its git history shows where it starts (2c7772ba30643b7a2026cbea938420dce7c6384d).

For local dev testing initially. Product-wise, it'll probably only be
workable on the two unsandboxed builds.

Make tailssh ask LocalBackend for the SSH hostkeys, as we'll need to
distribute them to peers.
For now only the hacky use-same-as-actual-host mode is implemented.
