OSX tests used specific version numbers to test for new features and
used the default Darwin/* for the old code. Reversed those tests so
that compatibility code is in a switch leg with a specific version and
newer systems take the default leg.

This should allow Python to build on OSX 10.1.1 (which jumps from Darwin/1.4
to Darwin/5.1 due to a new numbering scheme).
