patch 9.0.2082: test_channel may fail because of IPv6 config issue

Problem: test_channel may fail because of IPv6 config issues
Solution: Catch and skip the test, if getaddrinfo() fails with
'Address family not supported'

Mark tests as skipped when ch_open encounters E901

On some of the Debian build systems, the IPv6 channel tests fail because
`ch_open('[::1]:<port>', ...)` raises the error "E901: getaddrinfo() in
channel_open(): Address family for hostname not supported".

This appears to happen because getaddrinfo() can't perform the reverse
lookup for the ::1, which is a config issue on that system. Therefore,
instead of reporting a test failure, mark the test as skipped due to the
bad network config

closes: #13473
