scripts/arch-run: use ncat rather than nc.
On Red Hat 7+ and derived distributions, 'nc' is nmap-ncat, but on
Debian based distributions this is often netcat-openbsd. Both are
mostly compatible with the important distinction that netcat-openbsd
does not shutdown the socket on stdin EOF without also passing '-N' as
an argument which is not supported on nmap-ncat. This has the
unfortunate consequence of hanging qmp calls so tests like aarch64
its-migration never complete.
We're depending on ncat behaviour and nmap-ncat is available in all
major distributions.
