Update ubuntu-debootstrap (2015-04-21 debootstraps)

This is probably the last update before the `vivid` release, which is scheduled for Thursday!

Additionally (and perhaps even more noteworthy), this is likely the last update of `lucid`/`10.04` at all, since it's scheduled for EOL on next Thursday (April 30).
