Delete Sliced_heap::Block object when freeing.

Browse Source 
When a portion of the sliced heap gets freed, the corresponding block
gets removed from the list of blocks, and it's dataspace containing the
block gets detached, but it's destructor never gets called. This leads
to leaking capabilities, when Native_capability is implemented as
smart-pointer, because the destructor of Ram_dataspace_capability that
is part of the Block object gets never called.
