Unify kernel flavors in one PKGBUILD

[ventureoo]

Based on #941 changes, but with less drastic changes in PKGBUILD structure.

Closes #750
Closes #894

I considered doing profiles/flavors as well, but thought that would be restrictive if someone wants to build a custom kernel. I see that you added $_flavor but still kept the rest of the build options.

While this does solve the problem of having too many PKGBUILDs, I worry about the number of variables in the PKGBUILD. (although if u think about it, $_features just moves that into a string instead of a variable).

Aside from that, I don't have much problems with this. I'm fine with it if this gets merged instead of #941.

P.S. on moving rt to $_preempt, somehow that didn't come to mind. it seems fitting though. should probably go there regardless of any of these unification series(es?) gets merged.

Good job, thanks.

Didnt review yet fully, but the only problem I do see would be if I want not build a specific variant, e.g deckify/hardened whatsoever.

But likely I would just edit the script then.

In this case you just need to select cachyos flavor, which is used by default. It doesn't override any build options, so you can customize your build with environment variables as before.

it'll be a little bit of a problem if you want to build some customized handheld kernel with a different cpusched, since it currently overrides it to BORE.

Pull request overview

This PR consolidates multiple kernel “flavor” packages into a single linux-cachyos/PKGBUILD that is parameterized via a _flavor preset, and removes the now-redundant per-flavor PKGBUILD directories. It also updates local build helper scripts and the GitHub Actions workflow to build the new unified variants.

Changes:

• Unifies previously separate kernel flavor PKGBUILDs (bore/bmq/eevdf/server/deckify/rt-bore) into linux-cachyos/PKGBUILD using a new _flavor preset mechanism and _package_suffix.
• Updates packaging logic to use the appropriate strip tool (llvm-strip vs strip) during module signing and header packaging.
• Refactors docker-based build scripts and tweaks CI build invocation.

• These _flavor values (server/deckify) do not match the presets accepted by linux-cachyos/PKGBUILD (cachyos-server / cachyos-deckify), so the PKGBUILD will fail with "Invalid preset" for these builds.

build_pkg linux-cachyos -e "_flavor=server" -e _package_suffix=lto
build_pkg linux-cachyos -e "_flavor=deckify" -e _package_suffix=lto

• This condition checks for _flavor="deckify", but the preset names accepted earlier in the file use "cachyos-deckify". As written, the deckify-specific kernel config toggles will not be enabled when using the preset.

    if [ "$_flavor" = "deckify" ]; then
        echo "Enabling handheld configs"
