Steve Kowalik a84611d766 Replace security.ubuntu.com when setting mirror
The current method to rewrite the mirror URL in the ubuntu element will
only rewrite archive.ubuntu.com, which leaves the security URL alone.
This is probably not intended for people who are creating images behind
firewalls.

* To use different mirrors rather than the default of archive.ubuntu.com and
security.ubuntu.com, use the environment variable DIB\_DISTRIBUTION\_MIRROR
