gnulib-tool.py: Fix incorrect type hint.

When adding type hints I made a mistake. The 'filelist' passed to
'filter_filelist' should be marked 'list[str]' and not 'str'.

You can see this in GLModuleSystem.py with mypy [1]:

pygnulib/GLModuleSystem.py:595: error: Argument 2 has incompatible type "list[str]"; expected "str"  [arg-type]
pygnulib/GLModuleSystem.py:612: error: Argument 2 has incompatible type "list[str]"; expected "str"  [arg-type]
