update as the only changes were in files not packaged by this port
which only includes the logtail pieces and skips logcheck itself.
while there use MASTER_SITE_DEBIAN instead of ftp.de.debian.org
logtail displays lines from a standard text file and keeps track of the
offset of the end of the file so that subsequent runs only display new
lines. The file's inode is also recorded so that rotated logs can be
detected.
