gbproxy: Fix parser to accept GSM 24.008 Attach Req messages

Currently the parse expects a 'MS network capability' IE with
2 <= length <= 3 which is compliant to GSM 04.08, 9.4.1  but not to
GSM 24.008, 9.4.1 which specifies 3 <= length <= 9. Thus the parser
rejects messages with a length >= 4 (including length field).

This patch relaxes the length check to accept either range by
requiring 2 <= length <= 9.
