cmake: Fix for cmake < 3.0.0 swig python bindings.

Browse Source 
There is a bug in the UseSWIG.cmake file for cmake < 3.0.0
where it does not use the SWIG outdir correctly.

This fix instead sets the CMAKE_CURRENT_BINARY_DIR which is used
by UseSWIG.cmake to place the wrapper file (and other collateral).

Before (w/cmake < 3):

    build/src/dfrph/pyupm_dfrphPYTHON_wrap.cxx

After:

    build/src/dfrph/python2.7/pyupm_dfrphPYTHON_wrap.cxx
