Will Ross 2bd6022682 python: Restore the experimental DTrace patch 
The old patch had a lot of whitespace differences, and they were failing with
Python 2.7.4. In addition to removing the whitespace differences, configure.in
was removed from the patch, as configure is being patched already.

Closes Homebrew/homebrew#19257.
Closes Homebrew/homebrew#19203.
Closes Homebrew/homebrew#19400.
