setup-dchroot: merge from tor (genname split into function, ubuntu updates)

- split schroot base name generation into its own function
- if we build an ubuntu chroot, upgrade to the latest packages available
  in -updates and -security of their suite, since it seems they don't
  ever do point releases so you end up with a 4 year old openssl in your
  chroot.
