It's kind of kooky that we build boost-graph and boost-container as
part of the boost-python build, and then delete them, instead of
reusing them from boost-libs, but finding a way to do that will
require wading into the boost build system.  So let's just try to
make sure they're available for REQUIRES/PROVIDES analysis.

Adding this dependency is unlikely to be onerous -- applications
using boost-python are almost certainly going to need the rest of
boost anyway (and they already needed it for boost-graph and
boost-container!).
