Fix ebuilds and metadata: follow Gentoo conventions

- Update metadata.xml DOCTYPE to https
- Use proper indentation (tabs)
- Consolidate USE flags to single 'gui' flag
- Simplify longdescription
- Remove redundant dependencies (glibc)
- Sort dependencies alphabetically
- Remove empty IUSE declarations
- Clean up metadata formatting
