[SECURITY] Fedora 30 Update: proftpd-1.3.6c-1.fc30

ProFTPD is an enhanced FTP server with a focus toward simplicity, security, and ease of configuration. It features a very Apache-like configuration syntax, and a highly customizable server infrastructure, including support for multiple ‘virtual’ FTP servers, anonymous FTP, and permission-based directo ry visibility. This package defaults to the standalone behavior of ProFTPD, but all the needed scripts to have it run by systemd instead are included.
