Updated net/mikutter to 3.0.6
fix inode checks for NetBSD
fix inode check result rrd handling for all BSDish systems; if you use
xymon-4.3.17nb1 on *BSD you may have lots of inode<number>.rrd files
in /var/xymon/rrd, since it used iavail instead of the name of the
filesystem mount to identify the inode usage stats.
