MFC r196787

  Do the first step in removing lukemftpd from the base system. Disconnect
  it from the build.

  If you are using the FTP daemon, please consider using the port ftp/tnftpd
  which is the same FTP server, but newer and might have more/better
  functionality.

  This results in us providing only one ftp daemon by default.
