  Temporary files left under /var/tmp by mkinitramfs

Bug description:
  Test Case
  ---------
  1) confirm there are no mkinitramfs junk files in /var/tmp
  2) run 'sudo update-initramfs -k all -u -v'
  3) interrupt update-initramfs with Ctrl-C
  4) observe junk files in /var/tmp e.g. /var/tmp/mkinitramfs*

  With the version of initramfs-tools in -proposed you should see not
  have any leftovers in /var/tmp.

  I recently ran out of disk space on my / mount.  While looking for
  what consumed the disk I noticed a large number (130) of directories
  with names / paths beginning /var/tmp/mkinitramfs.  These directories
  seem to be either ~103 MB or ~927 MB in size.  Many of these files are
  months old, some are almost a year.

  Having had a quick look about for an explanation as to why these files
  are here and found Debian Bug #814345.  That explains that temporary
  files are left behind by the initramfs-tools if something fails in the
  process.  If this is the cause of my files then updating the Ubuntu
  package to version 0.123 should resolve this issue.
