    testing: fix make kvm-keys
    
    Which was part of: make kvm-shutdown make distclean make kvm-install make kvm-keys make kvm-test
    (must remember to add punctation to testing's web page)
    
    Seems the "wc" removed by f036c15404ce275583e9360b2d9cb84f6c4ac040
    doesn't want to go:
    
      make --no-print-directory kvm-keys-up-to-date
      The following keys are more than 7 days old:
      run 'make kvm-keys-clean kvm-keys' to force an update
    
    Off hand:
    - test -n $(ls) and test -n "$(ls)" are different (and different again to x=$(ls))
    - either way, will this run into the shell's arg/string limits (wonder if make can do this magic)
