test_db_base_plugin_v2: Skip a few tests on some platforms

netaddr (and its underlying libc inet_pton) produces different
representations of IPv4-compat addresses for different platforms.

Linux:
    >>> netaddr.IPAddress("::2")
    IPAddress('::2')
    >>>

OSX:
    >>> netaddr.IPAddress("::2")
    IPAddress('::0.0.0.2')
    >>>

As our API assumes Linux's way, skip affected test cases on
the other platforms.

Related-Bug: #1484837
