qcam: Support OpenGL ES 2.0
The GL_RG and GL_RED texture formats are not supported in OpenGL ES
prior to 3.0. In order to be compatible with OpenGL ES 2.0, use
GL_LUMINANCE_ALPHA and GL_LUMINANCE instead. The shader code needs to be
updated accordingly for GL_RG, as the second component is now stored in
the alpha component instead of the green component. Usage of the red
component is fine, the luminance value is stored in the red, green and
blue components.
