[Piglit] [PATCH 10/18] arb_geometry_shader4: Test input overrun.

[Fabian Bieler]

Test that linking fails if the geometry shader accesses more components than
are available.

ARB_geometry_shader4 spec 2.16.1:
"However, a program object, containing a shader object that access more input
vertices than are available for the input primitive type of the program
object, will not link."
