[Piglit] [PATCH] es2_compat: run glReleaseShaderCompiler and use a builtin

All that mesa does when releasing the shader compiler is clear its
builtins list. So make sure to use a builtin, and release the compiler
sooner, to trigger a bug in mesa.
This code sequence is hit by some core Android component.
