The old global tests don't work; get rid of them. Fix the values of the
Lua globals in the new test, and get rid of IEEE_802_11_AIROPEEK.
(Yes, if you have a Lua script that depends on IEEE_802_11_AIROPEEK
being defined, or that depends on the values of the Wiretap
encapsulations not changing, it breaks. Fix it.)
