BUG: Rename installed python executable to account for case-insistive system

Considering that the MacOSX build server uses Apple HFS file system that
is case insensitive for operation [1], the installed python
executable is copied in

  Slicer.app/Contents/bin/Python/

instead of

  Slicer.app/Contents/bin/

This commit rename the installed executable into "python-real" to account
for this.

For sake of consistency, the renaming is also applied for all platforms.
