sys-boot/woeusb-ng: add USE=gui

Add a gui USE flag instead of using optfeature for two reasons:

- Broken PYTHON_COMPAT (no maintainer, optfeature is easy to miss)
- Some desktop profile users consider gui a core feature, and they don't
  expect the woeusbgui script to be non-functional

Closes: https://bugs.gentoo.org/940445
