is* tests: Ensure needed .m4 files are packaged

[Bruno Haible]

This patch ensures that some tests modules have the .m4 files that they need,
not only indirectly by coincidence, but explicitly.


2023-03-25  Bruno Haible  <bruno@clisp.org>

        is* tests: Ensure needed .m4 files are packaged.
        * modules/isfinite-tests (Files): Add m4/exponent*.m4.
        * modules/isnan-tests (Files): Likewise.
        * modules/isnanf-tests (Files): Add m4/exponentf.m4.
        * modules/isnanf-nolibm-tests (Files): Likewise.
        * modules/isnand-tests (Files): Add m4/exponentd.m4.
        * modules/isnand-nolibm-tests (Files): Likewise.
        * modules/isnanl-tests (Files): Add m4/exponentl.m4.
        * modules/isnanl-nolibm-tests (Files): Likewise.
        * modules/isinf-tests (Files): Reorder.
