RAB parameters: add Extended Max Bitrate

Adjust test expectation in test-ranap.c.

This IE is seen in a "real life" pcap of hNodeB operation. We did not need it
so far, but add it to test the ip.access nano3G.

Comment from the future: the ip.access nano3G rebooted upon RAB Assignment
Request, and after adding/tweaking some IEs it stopped rebooting. This is one
of the changes that fixed the reboot issue. The changes have been tested
incrementally until reboots vanished, but it's not clear/hasn't been tested
whether omitting this change alone will cause reboots to re-appear.
