bug#39122: 27.0.60; occur: Add bindings for next-error-no-select

[Tino Calancha <tino.calancha@gmail.com>]

I wish having `next-error-no-select', `previous-error-no-select' bound to `n'
and `p' in the occur mode, as we have in *grep* buffer.

AFAICS, we have all the infrastructure and it's just a matter of define
the bindings at `occur-mode-map'.
