    chg: test: Replace testsock.pl and testsock6.pl with a Python tool

    Both interface-presence probes become one isctest.tools.testsock
    module: without arguments it sweeps the 10.53.0.* addresses read from
    ifconfig.sh.in (formerly testsock.pl), with explicit addresses it
    checks just those (formerly testsock6.pl).  The pytest runner performs
    the check in-process; start.pl and the legacy tests.sh call sites run
    the tool with $PYTHON -m.

    The IO::Socket::IP availability gate in testsock6() is gone with the
    Perl: the probe always runs now, so the IPv6 test sections it guards
    can no longer be silently skipped for lack of a Perl module.
