lib: use CONFIG_ENV to pick which env dir to build

Browse Source 
Previously, lib/Makefile just hard-coded env_dpdk in the list of
directories to build; this won't work if the user has chosen a different
env implementation via CONFIG_ENV (or configure --with-env).

Modify lib/Makefile so that the user can either put their env
implementation directly into SPDK's lib directory (like env_dpdk) or
outside of the SPDK tree (in which case the user must handle building it
before building SPDK).
