xdriver_xf86-video-intel: add upstream patches fixing fstat build errors

Attempting to build xdriver_xf86-video-intel version 2.99.917 with udev
results in compilation failures. The provided patches ([1], [2])
corrects the `implicit declaration of function 'fstat'` occurrences
during the building of this driver.

[1] http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=12af8a575d1518d40416f83195049157c3a062a5

[Thomas:
 - add upstream link to the git commits in the patches themselves
 - add James SoB line inside the patches themselves
 - add a comment above AUTORECONF = YES to indicate why it was added]
