CI: run scapy on aarch64, i386, ppc64le, s390x and x86_64 on PRs

[evverx]

The script takes the Fedora package, edits the spec file to make it compatible with the upstream test suite and then it's all run on all those architectures on the latest stable Fedora release and Fedora Rawhide. (Rawhide is kind of a testing relase but it's useful in terms of catching things like #4280 reproducible with relatively new packages only).

It was originally prompted by
#3847 (where the Debian autopkgtest was run on big-endian and 32-bit machines) and should hopefully make it easier to catch various issues before they land.

It has been tested since the beginning of 2023 so it should be stable at this point.

To get it to work the repository should be hooked up to Packit: https://packit.dev/docs/guide#github.

(If there are any issues it should be possible to contact the Packit folks directly: evverx#1 (comment))

Thanks for the PR !

This is working great BTW, thanks again.

I've ended up enabling the manual trigger, so one has to do a <SLASH> packit build to run it. I didn't want to abuse the packit infra, and we probably don't need to test those plateforms after every commit.

Makes sense. Though it isn't always obvious how PRs can affect it. For example I cherry-picked #4351 on top of my fork, removed -K manufdb, triggered Packit and it failed there even though the GH Actions are green: https://download.copr.fedorainfracloud.org/results/packit/evverx-scapy-2/fedora-rawhide-x86_64/07331856-scapy/builder-live.log.gz. I think it should be safe to trigger it before PRs are merged just in case.

In the meantime I'll send another PR to turn on the "netaccess" tests.
