[PATCH] sparse: Add 'leaf' to ignored attributes.

[Ethan Jackson <ethan@nicira.com>]

This patch adds the 'leaf' GCC attribute to the list of ignored
attributes.  Glibc uses this attribute causing the following
warnings in userspace projects:

  /usr/include/stdlib.h:514:26: error: attribute '__leaf__': unknown attribute
