[PATCH v2] dim: Automatically sign-off patches from others

[Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com>]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

It is very easy to forget that commiters should sign-off
patches not authored by themselves.

v2: Missed to make sob variable local and align with dim
    coding style. (Daniel Vetter)
