[Piglit] [PATCH 1/1] glsl-es-1.00: sanity.shader_test fragment needs default precision

[Tom Gall]

GLSL ES 1.00 spec 4.5.3 page 36:
"The fragment language has no default precision qualifier for
floating point types."

Adding default precision for float in the fragment shader
so this sanity testcase doesn't error out.
mediump is choosen since according to 4.5.2 page 34:
"The fragment language requires any uses of lowp and mediump to
compile without error.  Support for highp is optional."
