Delete mountpoint when tomb is closed (fix #149)

Browse Source 
two bugs were left behind by the last refactoring, one about
consistency of the mountpoint naming (now using $TOMBNAME everywhere,
without the added .tomb extension as per #180), the other about a
missing _sudo to prefix rmdir commands.

Test suite has been updated accordingly.

This fix introduces a mandatory condition for the next update: all
tombs must be closed when upgrading the tomb script, else it will not
be able to correctly close them.
