Arch's edk2-ovmf package installs split files (OVMF_CODE.fd +
OVMF_VARS.fd) instead of a single OVMF.fd. Updated the search
to check OVMF_CODE.fd paths first, with a find fallback.
QEMU boot command now handles both formats:
- Split: -drive if=pflash,format=raw,readonly=on,file=OVMF_CODE.fd
-drive if=pflash,format=raw,file=OVMF_VARS.fd
- Single: -bios OVMF.fd
