Resurrect archivers/bzip and assign maintainer

This port was removed due not having a publically available distfile.
That has been fixed per the PR with maintainership assigned to submitter.

Additionally:

• The patch-aa was renamed
• The patch-ab and patch-ac touched the same file; they were combined and renamed
• DragonFly support was added (hence the portrevision bump)
• GPLv2 license was annotated
• 80-column formatting was respected
• PLIST sorted
