flake8: Clean up complained-about unused imports

This also adds a "# noqa: F401" comment on an unused "import lzma",
which we are using it in a try/except block that is being used to
check if the lzma module is importable; of course it is unused.

v2: This turned out to be a little tricky.

    mesonbuild/modules/__init__.py had the "unused" import:

        from ..interpreterbase import permittedKwargs, noKwargs

    However, that meant that the various modules could do things like:

        from . import noKwargs # "." is "mesonbuild.modules"

    Which breaks when you remove __init__.py's "unused" import.  I
    could have tagged that import with "# noqa: F401", but instead I
    chose to have each of the module import directly from
    "..interpreterbase" instead of ".".
