i965: Fix is-renderable check in intel_image_target_renderbuffer_storage

Previously we could create a renderbuffer with format
MESA_FORMAT_R8G8B8A8_UNORM, convert that renderbuffer to an EGLImage,
then FAIL to convert the EGLImage back to a renderbuffer because
reasons.  Just use the same check in
intel_image_target_renderbuffer_storage that brw_render_target_supported
uses.

There are more checks in brw_render_target_supported, but I don't think
they are necessary here.  A different approach would be to refactor
brw_render_target_supported to take rb->Format and rb->NumSamples as
parameters (instead of a gl_renderbuffer) and use the new function here.

Fixes:

    ES2-CTS.gtf.GL2ExtensionTests.egl_image.egl_image
