[gjs/esm/static-imports] tests: Add ES module static import tests

[Philip Chimento <pchimento src gnome org>]

commit 95c5a0d58a1361e055472da42510c7ef96402cb9
Author: Philip Chimento <philip chimento gmail com>
Date:   Wed Dec 9 15:12:37 2020 -0800

    tests: Add ES module static import tests
    
    Adds an '-m' flag to minijasmine, to execute the given file as a module.
    (No fancy command line parsing is done; the -m must come after the file
    name.)
