heredoctest: use the same dict for local/global contexts as in doctest

In order to mimic module-level evaluation, globals and locals should be the
same object, so doctest does not pass separate locals dict.

https://docs.python.org/2.7/reference/simple_stmts.html#exec

This fixes NameError in the following example:

    >>> import foo
    >>> def bar():
    ...     foo  # must exist in globalvars
