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.
