EGL: translate EGL_GL_COLORSPACE_LINEAR_KHR to UNKNOWN
EGL_GL_COLORSPACE_KHR affects how GL blends and how the window
system interprets the pixel values. Since LINEAR is the default, we
should treat it as we traditionally do
- linear GL blending
- UNKNOWN dataspace
The prior behavior is no longer possible until some new EGL extension
adds something like EGL_GL_COLORSPACE_SRGB_LINEAR.

Test: boots and dumpsys to confirm
