Subject: tests/scripts/common.sh: avoid IPv6 in check_if_port_*
X-Git-Tag: 3.8.12~7^2

tests/scripts/common.sh: avoid IPv6 in check_if_port_*

I've encountered a race condition when IPv4 couldn't bind, IPv6 did bind,
the check passed because IPv6 could bind,
but then tlsfuzzer testsuite used IPv4 and failed.
One of the simplest solutions is to filter out IPv6 in the checks.
