mesa: Flag _NEW_BUFFERS when unbinding an attachment on glDeleteTextures.

The _ColorDrawBuffers[] wouldn't get updated despite us having updated
what it depends on (Attachments[]->Renderbuffer).  Other callers of
_mesa_remove_attachment are already flagging _NEW_BUFFERS for other
reasons.  The specific bug report that led to this fix (and
the fbo-finish-deleted testcase) was fixed by
23b6f9606dc247488835745668b3686218612536, though.
