Partially revert "python: futurize -f libfuturize.fixes.fix_absolute_import"

Since commit 068cf7a44cd4d65c05aa877dbebced295be5ce44, qmp-shell
is broken:

  $ ./scripts/qmp/qmp-shell
  Traceback (most recent call last):
    File "./scripts/qmp/qmp-shell", line 70, in <module>
      from . import qmp
  ValueError: Attempted relative import in non-package

Relative imports don't work on scripts that are executed
directly, so revert the change on the scripts inside scripts/qmp.
