- Update `sysutils/unetbootin' to version 661, which had added support for

Ubuntu 18.04 and some minor bugfixes
- The project had moved to GitHub from SF, but do not switch to USE_GITHUB
  just yet (distfile size would be 16257579 bytes in this case, apparently
  because upstream does not know how to prepare GitHub releases properly)
- Amend the regex when patching `main.cpp' for better ${PREFIX} support:
  previously it was not covering `/usr/bin/unetbootin'
