    CI: Remove all use of /bin/false as a ROM
    
    As the recent work to get PCI Passthrough testing working shows, putting
    `/bin/false` as a ROM into guest context doesn't work so well.
    
    For all ROM paths where we're skipping the build, use a slightly-plausible 
but
    likely non-existent path instead.
