[Dovecot] quotactl failed with disk quotas and dovecot 2.0

[Patrick McLean]

Ok, so it appears that this entry in my mtab was causing dovecot to get
confused:

> rootfs on / type rootfs (rw)

So here is a little patch to make dovecot ignore filesystems of type
"rootfs". This seems to fix the problem for me as it just finds the
proper mtab entry for the root filesystem.
