meta-zephyr-sdk: qemu: Use Zephyr SeaBIOS fork binaries

The original change making QEMU use Zephyr SeaBIOS fork,
1bf6f4a, was dropped by mistake during
the upgrade to QEMU 10.0.2.

This commit updates the QEMU recipe to use the pre-built x86 BIOS
binaries from the Zephyr SeaBIOS fork.

The Zephyr SeaBIOS fork contains a few additional patches to make
debugging more convenient for x86 QEMU targets (e.g. not clearing screen
on reset).
