[PATCH 05/13] remote rm: handle symbolic refs correctly

In the modern world of reference backends, it is not OK to delete a symref by unlink()ing the file directly. This must be done via the refs API.

We do so by adding the symref to the list of references to delete along with the non-symbolic references, then calling delete_refs() with the new flags option set to REF_NODEREF.
