BUG-6712: fix bin/shell's classpath

bin/shell is duplicated from Karaf, but needs ${karaf.version} instead
of ${project.version} to define its classpath.

The correct long-term fix is to drop bin/shell and rely on upstream's
version (https://git.opendaylight.org/gerrit/45546); this patch is
intended for cherry-picking to Boron.
