Github only hosts a limited number of platforms, and the runner code
is only supported on slightly wider range of platforms. To increase
our test coverage beyond that, we run the runner natively on a VM host,
where it runs a jobs that boot VMs of other platforms, waits for them
to come up then runs the build and test by ssh'ing into the guest.
This means that the minimum dependencies for the guests are quite low
(basically just sshd, a compiler and make).
The interface to the VM host is fairly simple (basically 3 scripts:
vmstartup, vmrun and vmshutdown), but those are specific to the VM host
so are not in the public repo. We also mount the working directory on the
host via sshfs, so things like artifact upload by the runner also work.
As part of this we are moving the per-test-target configs into a single
place (.github/configs) where there will be referenced by a single short
"config" key. I plan to make the github-hosted runners use this too.
The self-hosted runners are run off a private repo on github since that
prevents third parties from accessing them[0], and since runner quota is
limited on private repos, we avoid running the tests we run on the public
repo.

Some systems don't have a hostname command (it's not required by POSIX).
The do have uname -n (which is), but as found by tim@ some others (eg
UnixWare) do not report the FQDN from uname -n.
out uname -n doesn't do what we need for some platforms in portable, so we'll
fix the original problem (that some other platforms don't have hostname at
all) by providing wrapper function to implement it.

accurately reflects its effect. This matches a previous change to
PubkeyAcceptedAlgorithms. The previous names are retained as aliases. ok
