Jim Harris d132ee3531 build: use DEPDIRS variables to build SPDK_LIB_LIST
All of our Makefiles duplicate huge lists of libraries
in SPDK_LIB_LIST.  We have a very precise and accurate
accounting of the library dependencies in
mk/spdk.lib_deps.mk which can be used to generate
the full list if the app specifies the modules and
subsystem libraries it wishes to link.

I did a first pass through all of the existing
Makefiles to take advantage of this new functionality.
There may be more optimizations we can make later but
don't want to hold up this patch for all of them.
