cyrus-admin installs broken symlinks to sieveshell and installsieve

[Max Bowsher]

maxb@altimeter:~$ ls -lA /usr/bin/sieveshell
lrwxrwxrwx 1 root root 13 Jul 25 13:19 /usr/bin/sieveshell -> ../sbin/cyrus
maxb@altimeter:~$ ls -lA /usr/sbin/sieveshell
ls: cannot access '/usr/sbin/sieveshell': No such file or directory
maxb@altimeter:~$ ls -lA /usr/lib/cyrus/bin/sieveshell
-rwxr-xr-x 1 root root 10501 Jul 25 13:19 /usr/lib/cyrus/bin/sieveshell

It would appear the utilities have been relocated but the installed symlinks still point to a previous location.
