    libacpi: Pass missing --dm_version to mk_dsdt
    
    Commit 19ab8356abe4 ("tools: remove support for running a guest with
    qemu-traditional") made passing --dm_version to mk_dsdt mandatory on
    x86 but didn't fix all the invocations of it.
    
    The previous default was qemu-xen-traditional so with that removed set
    the dm_version to qemu-xen for this invocation.
    
    Without this change, Xen fails to build on x86 when using
    --enable-rombios.
    
    Fixes: 19ab8356abe4 ("tools: remove support for running a guest with 
qemu-traditional")
