This commit removes MEMPOOL_IS_CONTIG().
The next commits will change the behavior of the mempool library so that
the objects will never be allocated in the same memzone than the mempool
header. Therefore, there is no reason to keep this macro that would
always return 0.
This macro was only used in app/test.
