library/gsup: distinguish GSUP_MT_FORWARD_SM_ERR_{MS,NET}

The idea is to have two variants of the MT_FORWARD_SM_ERROR:

* _MS: originated by the MS/UE (via RP-ERROR), * _NET: originated by the network itself.

The network-originated kind will be used to indicate unsuccessful delivery of a MT SMS in absence of response from the MS/UE.
