tests: Use socat instead of netcat
Commit 41c02e10 ("tests: Use nmap-ncat instead of openbsd netcat for pasta
tests") updated the pasta tests to use the nmap version of ncat instead of
the openbsd version, for greater portability.
For some upcoming changes, however, we'll be wanting to use socat.
"socat" can do everything "ncat" can and more, so let's move all the
tests using host tools (either directly on the host or via mbuto
generated images) to using socat instead.
