camera2/legacy: Fix expected errors on eglSwapBuffers

SurfaceTextureRenderer::swapBuffers interpreted EGL_BAD_SURFACE as
indicating an abandanoned buffer queue. But the EGL 1.4 lists additional
errors that also indicate extreme failure: EGL_CONTEXT_LOST, and
EGL_BAD_NATIVE_WINDOW.

Discovered while debugging CTS test
android.hardware.camera2.cts.RobustnessTest#testAbandonRepeatingRequestSurface
on ARC++ x86 boards.
