Add -l option to src-release script.

Since we are updating src-release.sh I thought I would check in this
small patch.  It adds the option to create lzip compressed tarballs
via the -l command line option.

	* src-release.sh (LZIPPROG): New define.  Provides the name of the
	lzip program.
	(do_lz): New function.  Compresses a tarball using the lzip
	program.
	(do_compress): Add support for lzip compression.
	(usage): Mention -l option.
	(build_release): Support -l option to invoke lzip compression.
