[Boost-build] Patch for python.jam to support paths with spaces.

   Hi.

   The attached patch made the capture-output testing rule in python.jam 
work correctly when the path to the used Python executable includes spaces.

   It simply quotes the used Python executable before using it in the 
actual command line so it should not be destructive. On the other hand, 
something like this failing could mess up Boost Build testing which is 
something we do not want this close to the release.

   I ran the Boost Python tests with this patch on Windows and all 
passed fine.

   Anyone see any objections to commiting this patch?

   Best regards,
     Jurko Gospodnetiæ
