    pkgbase: examine METALOG files relative to stage root directory
    
    Previously we stripped the '.' from the beginning of each METALOG entry
    to determine the path to stat.  This meant that we examined files on the
    build host, not the staged files.
    
    Instead, strip off the last part of the specified METALOG pathname to
    find the stage root directory, and stat files relative to that.
