charliecloud-0.18-bp152.2.4.1

- Update to version 0.18
  - Fixes an important symlink handling bug in ch-tug and ch-grow.
    Prior to version 0.18, if a pulled image contained a symlink in one
    layer and then a regular file at the same path in a subsequent layer,
    the *target* of the symlink would be overwritten even if it was
    not within the image; i.e., unpacking inappropriately followed
    the symlink. This allows a crafted image to overwrite any file
    writeable by the invoking user.
    Because Charliecloud is unprivileged, other files on the system,
    e.g. system files, are unaffected.
  - ch-grow: --version and --help work w/o dependencies installed
    new switch --list to list images
    now gives diagnostics for syntax errors and unsupported instructions
    WORKDIR now supports relative paths (#786)
    no longer crashes if input doesn’t end in newline (#474)
