    Fix non-standard inherented modes of directories in debuginfo
    
    In case that binary compiled from source generated in /tmp, a
    /usr/src/debug/tmp directory will be created with the same mode as
    /tmp, a.k.a 777, which should be avoided.
    
    Fixes: rhbz#641022

commit e795899780337dea751d85db8f381eff3fe75275

    debugedit: Only output comp_dir under build dir (once).
    
    The fix for rhbz#444310 (commit c1a5eb - Include empty CU current dirs)
    was a little greedy. It would also include comp_dirs outside the build
    root. Those are unnecessary and we don't have a good way to store them.
    Such dirs (e.g. /tmp) would then show up at the root of /usr/src/debug.
    
    Fix this by including only comp_dirs under base_dir. Also only output
    all dirs once (during phase zero) and don't output empty dirs (which
    was harmless but would produce a warning from cpio).
    
    This still includes all empty dirs from the original rhbz#444310
    nodir testcase and it is an alternative fix for rhbz#641022
    (commit c707ab).
    
    Both fixes are necessary in case of an unexpected mode for a directory
    actually in the build root that we want to include in the source list.
