The requested ES version gets passed directly to waffle. So, if
a test stupidly sets `supports_gl_es_version = 25`, then 2.5 gets
passed to waffle_context_create and then to eglCreateContext, and should
fail there. In other words, there does exist a safeguard against stupid values.

Good! This is the one point in the series that I feared a NAK. I was really
hoping no one wanted a piglit_gl_test_config::supports_gl_es3.

Fixed.
