[Piglit] [PATCH 2/2] android: add strchrnul to shader_runner.c

[Tom Gall]

strchrnul is used in shader_runner.c (and no where else in all
of piglit). Unfortunately bionic, Android's c library does not
include this function. I've writen an implementation of
strchrnul which is only used when compiling for Android.
