Raspbian support

[fenhl]

According to this comment, an output of NEEDRESTART-KSTA: 0 means an unknown result. What are possible causes for this? I have installed needrestart on a Pi running Raspbian and it has been displaying this ever since.

needrestart is looking for kernel images with a usual name at /boot/vmlinu*. On Raspbian the image is /boot/kernel.img which is not handled by needrestart.

It was a trival patch to support Raspbian:

[Kernel/Linux] Expected linux version: 4.4.13-v7+
Running kernel seems to be up-to-date.

So it seems to work as expected.
