maint: make copyright statements more consistent; update gnulib

* cfg.mk (update-copyright-env): Add UPDATE_COPYRIGHT_FORCE=1
to rejoin some split lines, and UPDATE_COPYRIGHT_USE_INTERVALS=2
to make update-copyright use only one year range.
* gnulib: Update.
* testsuite/files0-from: Adapt to gnulib's change from `q' to 'q'.
