    toolchain-shar-extract.sh: add option to list contents
    
    Add a -l command-line option for SDK installers to get a list of files
    that will be extracted by the SDK - internally this just runs "tar tv"
    on the embedded tarball. This can be used to look at which files the SDK
    provides without actually installing it. The initial user of this is the
    extensible SDK build process which needs to know what binaries are going
    to be installed by the buildtools installer without installing it.
