Firmware cleanup 2021

[AdamWill]

This PR includes a few commits to drop various probably-unnecessary firmware files in runtime-cleanup, to save about 30M on network install images. This will help with them being oversize for F35 and Rawhide currently.

tweaked the last commit to just leave liquidio and netronome firmwares out entirely at install stage; @nullr0ute says to do this in https://bugzilla.redhat.com/show_bug.cgi?id=2011615#c3 .

You can probably drop ipw2100-firmware and ipw2200-firmware as they were only ever sold on i686 machines, and while I'm sure there's someone that has salvaged them and have them in another device I doubt they're using netinst.

thanks. they're pretty tiny, though, they barely add up to a megabyte, so might not be worth bothering with!

These all seem reasonable to me, thanks for including explanations with each, I think it's important to do that since I have no real idea of what firmware blobs are really used and which aren't :)

[AdamWill]

Thanks! As I'm intending these changes to help us get the F35 images under size, can you do a new release/build/update for F35? I can just backport the patches if you'd prefer, just let me know :)

Thank you!

FYI, I have a private TODO to re-examine the packages on boot.iso. I looked at that a few months ago and there are just so many things that make zero sense at first glance that it's hard to believe. I think the buildup to F34/RHEL9 brought a lot of stuff through some kind of churn. However I didn't check how many of these are cleaned up by the templates.

My idea was to write a script to go through lorax-packages.log, check if the package files are actually present, take stock of what actually remains, then eyeball the data to see if there is anything outright useless. If anyone beats me to it... ;-)

That probably needs a bug and an exception doesn't it? Since we're past the final freeze date.

Inertia is a better description :) I tend to make minimal changes once something has been added since it's hard to know what really depends on it. IIRC the majority of the growth over time has been the firmware blobs but I'm sure there's room for improvement in other areas.
