Lower dependency on Storable to 2.20.

The Debian squeeze system has only 2.20, and the 2.21 does not
seem to be required for all tests to pass. Also, checked with
Galen Charlton and Henri-Damien LAURENT (who added the 2.21
dependency) on IRC that 2.21 did not have anything that was
required, compared to 2.20.
