    release: Fix typo in powerpc mkisoimages.sh
    
    "[ n foo ]" is an error and should have been "[ -n foo ]".
    
    Fortunately the only ill effect was to result in garbage in /tmp/ when
    creating powerpc ISO images.
    
    Fixes:  6c3e01bf8578 ("release: Randomize powerpc boot block file name")
