Implement the XOR-2G authentication algorithm

We've so far only been supporting XOR-3G algorithm as specified
in TS 34.108 (in both 3G and 2G-derivation mode).

However, XOR-3G used for 2G auth is different from the XOR-2G algorithm
as defined in Annex A of TS 51.010-1.  Let's add support for that one,
too.
