[kvm-unit-tests PATCH v2 10/10] x86 UEFI: Make _NO_FILE_4Uhere_ work w/ BOOTX64.EFI

[Zixuan Wang <zxwang42@xxxxxxxxx>]

From: Marc Orr <marcorr@xxxxxxxxxx>

The `_NO_FILE_4Uhere_` test case is used by the runner scripts to verify
QEMU's configuration. Make it work with EFI/BOOT/BOOTX64.EFI by compling
a minimal EFI binary, called dummy.c that returns immediately.
