ftp/wzdftpd: resurrect^Wreadd previously deleted port

Despite that original author stopped working on the project, it has
its userbase and remains fairly popular and demanded, known for its
versatility and capabilities, so:

• Bring back from the attic and fix the build with -fno-common
• Mark OPENSSL option as BROKEN for the time being
• Expand the default options a bit to get more useful package
• Tighten one regex (escape the dot) and kill stray backslash
• Fix a typo and adjust WWW line in the port description text
• Submitter assumes maintainership of the port (thanks!)
