Ensure all are "normal" versions according to the new version scheme
introduced in OTP 17.0

This is just a preparation to allow detection of older nodes
that do not understand maps (R16 and older).

to be: 116,Arity, K1,V1,K2,V2,...,Kn,Vn

instead of: 116,Arity, K1,K2,...,Kn, V1,V2,....,Vn

We think this will be better for future internal map structures
like HAMT. Would be bad if we need to iterate twice over HAMT
in term_to_binary, one for keys and one for values.

Let Maps be tested in the suite.

The API and implementation are simplistic, like for lists and tuples,
using arrays and without any connection to java.util.Map.

* maint:
  Add smoke tests

Smoke tests are meant to verify that a build of erlang has been successfull.
