extensions: rk-panthor: mesa-oibaf + DEFAULT_OVERLAYS="panthor-gpu"

• extensions: rk-panthor: mesa-oibaf + DEFAULT_OVERLAYS="panthor-gpu"
  • I had worked this before AF sent his oneliner, but I forgot to PR
  • Should be the same, except avoids sadness when trying with the wrong kernel/branch

@monkaBlyat (renamed from our first incarnation of this), otherwise is the same

I need some help for perfect extension matching here: https://github.com/armbian/os/blob/main/userpatches/targets-extensions.map

v4l2loopback-dkms, rk-panthor, rk-panthor, mesa-oibaf ...

Fixed mess, now a single thing (rk-panthor) Should work exactly the same except adds -panthor suffix to images and checks valid kernel/branch.
