    firmware/shim: avoid mkdir error during Xen tree setup
    
    "mkdir -p" reports a missing operand, as config/ has no subdirs. Oddly
    enough this doesn't cause the whole command (and hence the build to
    fail), despite the "set -e" now covering the entire set of commands -
    perhaps a quirk of the relatively old bash I've seen this with (a few
    simple experiments suggest that commands inside () producing a non-
    success status would exit the inner shell, but not the outer one).
    
    Add a dummy . argument to the invocation.
