qhull 2012.1

Upgrade qhull to version 2012.1
Adjust the patch for this version and put it inline.
Patch doesn't need to remove `user_eg user_eg2 user_eg3` anymore
because the test programs are not built by default.
Remove the CMake variable to adjust the man page location which
it gets correct now.
Put the source directory last on the `cmake` command line.
Tested on Lion using clang and llvm from XCode-4.3.3 by using
the examples provided in the `qhull` usage.

Closes Homebrew/homebrew#12911.
