tests: update test-remotefilelog-gc.t for Python 3.11

The test output changed because test coverage changed because normpath changed:

  $ python3.10 -c 'import os; print(repr(os.path.normpath("asdas\0das")))'
  'asdas\x00das'

  $ python3.11 -c 'import os; print(repr(os.path.normpath("asdas\0das")))'
  'asdas'

#require docutils gettext
