This parameter is the name of the varbind to be added.
It's inherently of type Object ID, so the size is the
number of subidentifiers:

> size_t objid_snmptrap_len =OID_LENGTH(objid_snmptrap);
which is exactly what you have.
However, the final parameter pair:

> (u_char *)notification_oid, notification_oid_len);
is the value to be assigned to this varbind.
This can be of any type (integer, string, ObjectID)
so the size is the size of the whole value.
In *bytes*, not subidentifiers.

You are passing the number of subidentifiers (32-bit values),
but the library is taking this as the number of bytes (8-bit values).
So it's only using the first quarter of the value.
Try
size_t notification_oid_len = sizeof(notification_oid);
