Updated sysutils/dc-tools to 1.3

changes to dc-burn-netbsd
- rename 'extract sets' from -r to -s
- Split out the code to adjust the extracted data for live CD usage and enable
  via '-l'. Make -l imply '-s base -k GENERIC' unless overridden
- Tweak live setup further to speed up slightly and avoid rebuilding the
  X11 fontcache, sort rc.conf, set dhcpcd=YES & tweak root entry in fstab
- Disable burning to CD by default and add -b to enable
- Add support for listing and downloading/burning the daily NetBSD
  branch builds from nyftp.netbsd.org
