Add test case about RANAP MaxBitrate encoding

Our version of asn1c/libasn1c used to have an INTEGER encoding but,
where the encoding of integers of > 2 bytes length was broken.

Add a test case to what we expect with the updated/fixed libasn1c.

If your compilation breaks, please upate to libasn1c with related
fix commited a few minutes ago.
