Otherwise there are problems when user overrides version and application
such as Piglit wants to detect used api with glGetString(GL_VERSION).
This makes it currently impossible to run glslparsertest tests for
OpenGL ES when using version override.
Below is example when using MESA_GLES_VERSION_OVERRIDE=3.1.
Before:
"3.1 Mesa 11.1.0-devel (git-
24a1a15)"
After:
"OpenGL ES 3.1 Mesa 11.1.0-devel (git-
78042ff)"
v2: only include api prefix for OpenGL ES (Boyan Ding)
