tests: Use nmap-ncat instead of openbsd netcat for pasta tests

Browse source 
A number of the testcases use options specific the OpenBSD version of
netcat.  That's available in Debian, but not easily available in Fedora.
Switch the pasta tests to using the nmap version of netcat (a.k.a. ncat).
This is easily available in both Debian and Fedora, and appears to be a
bit more modern and maintained as well.

ncat generally requires explicit listen addresses (which is good for
clarity anywhere).  Its default options appear to remove the need for the
-N and -q options.
