[Mesa-stable] [PATCH] svga: Fix incorrect advertizing of EGL_KHR_gl_colorspace

[Thomas Hellstrom]

When advertizing this extension, egl_dri2 uses the DRI2_RENDERER_QUERY
extension to query whether an sRGB format is supported. That extension will
query our driver with the BIND flag PIPE_BIND_RENDER_TARGET rather than
PIPE_BIND_DISPLAY_TARGET which is used when building the configs.
We only return the correct value for PIPE_BIND_DISPLAY_TARGET.

The inconsistency causes EGL to crash at surface initialization if sRGB is
not supported. Fix this by supporting both bind flags.

Testing done:
piglit egl_gl_colorspace srgb
