xwayland: do not disable glamor if EGLStream failed

Browse Source 
EGLStream requires glamor, but the opposite is not true. So if someone
passes "-eglstream" with a GPU which does not support EGLStream, we
could maybe still try GBM and be lucky.

That allows Wayland compositors to pass "-eglstream" regardless of the
actual hardware, if they want to enable EGLStream on GPU which support
it.
