Tests fail on Packit

[evverx]

It's more of a downstream issue but since it's triggered upstream from time to time I'll file it here so as not to forget about it.

With #4975 merged all the jobs started failing because the downstream import check in the spec file isn't aware of scapy.arch.windows.sspi and fails with

Failed to import: scapy.arch.windows.sspi

I'll send a patch removing the downstream import check from the spec file in .packit.yml.

The test also fail on big endian machines with

###(015)=[failed] Configuration conf.use_pcap

>>> if not conf.use_pcap:
...     assert not conf.iface.provider.libpcap
...     conf.use_pcap = True
...     assert conf.iface.provider.libpcap
...     for iface in conf.ifaces.values():
...         assert iface.provider.libpcap or iface.is_valid() == False
...     conf.use_pcap = False
...     assert not conf.iface.provider.libpcap
... 
AssertionError

I tracked it down and it's because pcap_findalldevs fails with

b'eth0: SIOCETHTOOL(ETHTOOL_GLINK) ioctl failed: Inappropriate ioctl for device'

It started failing because fedora-copr/copr#4219 was temporarily addressed by switching to VMs in https://forge.fedoraproject.org/infra/ansible/pulls/3232. I'm not sure that environment is suitable for running the scapy tests currently so I'd just turn off the big-endian jobs for now.
