I was able to use the commands I showed before successfully but only after
making these changes:

This is a hack obviously but it fixes the issues my particular setup has:
- By asking for "localhost" we get the IPV6 interface first and the QEMU VM
doesn't have IPV6 to the host. (I'm sure it could with some extra setup)
- "0.0.0.0" fixes that issue since it's an IPV4 special address. (and means the
port can be connected to externally?)
- Then we were telling lldb-server in the VM to connect to a local port, not to
the port on the host. getfqdn fixes that.
So I end up with the host side listening to `0.0.0.0:<port>` and lldb-server in
the VM connecting to `<host's hostname>:<port>` and that works.
If we want this scenario to work (and it's not a dodgy network setup on my
part) perhaps we could take a hint from how we're connected to the initial
platform?
Connecting to remote platform 'remote-linux' at 'connect://<VM IPv4
address>:54321'
So here we could assume that IPv4 is ok and since the hostname isn't any sort
of localhost we need to tell the lldb-server to connect to the hostname of the
machine running the tests.
(though that assumes you can in fact connect to that from the VM, with what I
have, you can)
