[ovs-dev] [PATCH] tests: Fix test that tests if the system doesn't support IPv6

Currently if IPv6 is globally disabled (net.ipv6.conf.all.disable_ipv6=1) or
if IPv6 is disabled on loopback interface (net.ipv6.conf.lo.disable_ipv6=1)
the check doesn't work since no interface have ::1 and EADDRNOTAVAIL is

This causes a Python exception to be printed, like this:

Traceback (most recent call last):
  File "<string>", line 6, in <module>
  File "/usr/lib64/python2.7/socket.py", line 228, in meth
    return getattr(self._sock,name)(*args)
socket.error: [Errno 99] Cannot assign requested address

In this case HAVE_IPV6 is not set and all IPv6 tests fails.
This commit fixes the problem by check also for EADDRNOTAVAIL.
