Basemap uninstall fix.

Creating an upper bound on basemap constraint.

Currently trying to install it yields:

conda create --dry-run -n bm_test basemap

The note on the constraint mentions this issue https://github.com/ContinuumIO/anaconda-issues/issues/11590. It may have been misdiagnosed. basemap did do a small reorg in 1.3.0 where it states it put enough data to be functional. I think this constraint should be the right place to protect the past but enable the future.
