Vsftpd: import from oldpackages

Two commits are included: 
First is a straight copy from oldpackages, 
Second adds TLS/SSL example options to config (commented out, so that they do not disturb the non-SSL version). Copyright year has been bumped.

I did not add myself as the maintainer, as the package already had one defined.
