Add a -S/--strip-path option

Often times it's nice to create a "raw" tarball which does not include the
package name in its paths.

Compare old method:
 $ rpm2targz pkg-ver.rpm
 $ tar tf pkg-ver.tar.gz
 ./pkg-ver/<files>
With new method:
 $ rpm2targz -S pkg-ver.rpm
 $ tar tf pkg-ver.tar.gz
 ./<files>
