KHR-GL3{0,1,2,3}.api.coverage's ReadBuffer coverage sub-test captures
GL_READ_BUFFER while dEQP's own fbo-surface-type wrapper FBO is bound
(a real, non-zero-named FBO, not framebuffer 0), then later deletes an
unrelated FBO of its own. Per the GL spec, deleting a bound FBO
implicitly rebinds framebuffer target 0 - the true default framebuffer
this time, not the wrapper - and restoring the captured
GL_COLOR_ATTACHMENTn value against it correctly raises GL_INVALID_ENUM
(only FRONT/BACK-style tokens are valid there). This is a spec-correct
response to a --deqp-surface-type=fbo-only test-methodology artifact,
not a MobileGL conformance defect, and cannot occur on a real
window/pbuffer-backed run where framebuffer 0 is genuinely bound
throughout. Add a waiver (dEQP's own mechanism for exactly this kind of
known non-defect) instead of weakening the (correct) validation, and
wire --waiver-file through run_cts_local.py.
