Fix submitted upstream

[Launchpad Janitor (janitor)]

This bug was fixed in the package grub-installer - 1.27ubuntu2

---------------
grub-installer (1.27ubuntu2) hardy; urgency=low

  [ Colin Watson ]
  * udev 117 merged all udev tools into a single binary called udevadm.
    Check for this and use it instead of udevinfo if available.

  [ Evan Dandrea ]
  * Handle cases where /boot is bindmounted (LP: #181658).
