http://bugs.debian.org/816513
Ignore any error from initramfs-tools' "configure_networking".

* initramfs-tools-script: Wrap call to "configure_networking" with
  "set +e" and "set -e", since configure_networking was not designed
  to run in a "set -e" environment.

Closes: 816513
Thanks: Carlos Alberto Lopez Perez <clopez@igalia.com>
