[ Upstream commit 5e8670610b93158ffacc3241f835454ff26a3469 ]
The test relies on 'nc' being the netcat version from the nmap project.
While this seems to be the case on Fedora, it is not the case on Ubuntu,
resulting in failures such as [1].
Fix by explicitly using the 'ncat' utility from the nmap project and the
skip the test in case it is not installed.
