gnulib-tool: license of tests modules

[Bruno Haible]

Test module descriptions don't have a license statement of their own.
When "gnulib-tool --create-testdir --with-tests" is used, it emits a
warning:

warning: module iconv depends on a module with an incompatible license: 
iconv-tests

This fixes it.

        * gnulib-tool (func_get_license): For test modules, use the license of
        the main module.
