mesa/main: do not allow integer-texture enums before gles3

Integer textures shouldn't be implicitly exposed on OpenGL ES 1.x and
2.x, but because the code checked against a driver-capability rather
than using an extension-check helper, we ended up accidentally allowing
these enums on older versions when the driver supports it.
