We don't really need to link the env for these unit tests.
We were doing it mostly for convenience. We can easily
leave out the env library, and just define a few stubs
for the functions that the memory unit tests call.
This helps prepare for the next patch that will use
rte_malloc/rte_free to allocate mapping structures. By
not linking the env libraries, we can just stub
rte_malloc/rte_free with simple malloc/free, rather than
doing a full env initialization to get rte_malloc/rte_free
working.
