Subject: [PATCH] feat(qemu): disable Xen support

Azure Linux targets Hyper-V/KVM, not Xen. Since our builders have the
%fedora macro set, the upstream spec enables Xen on x86_64/aarch64 by
default, pulling in xen-devel at build time and libxenstore.so.4 at
runtime.

Override have_xen back to 0 via overlay. Verified: build succeeds and
no output RPMs carry xen dependencies.
