hyprpm: check for abi strings in headersValid

[vaxerski]

Because we now properly include ABI info in our version string, hyprpm should take that into account when checking if we need to update.

Ref outfoxxed/hy3#254
Ref hyprwm/hyprland-plugins#552

Needs a quick test

@VirtCode have you had a chance to verify this is working

I don't use hyprpm myself but I can quickly have a look whether things still work as expected (could also try to simulate an ABI break with some downgrading but I'll see). Will be back later this evening, need to finish an assignment first.

Okay finally got around to it. Currently hyprpm update does not work with an empty cache. Always fails with "ABI is mismatched.", even with --force. So to reproduce, just run hyprpm purge-cache and then hyprpm update.

I had a quick glance at the code and I guess the issue is that headersValid() checks against the hash in the global state, and fails if it doesn't match. In our case the global state doesn't exist yet as we seem to write it after checking header validity? But a similar thing would happen if our state contains an old hash, so I don't know whether that's really what's happening.
