checkpatch: Only consider certain signoffs

Formatted patches can contain a heirarchy of sign-offs.  This is true when
merging patches from different projects (eg. backports to the datapath
directory from the linux net project).

This means that a submitted backport will contain multiple signed-off
tags, and not all should be considered.

This commit updates checkpatch to only consider those signoff lines which
start at the beginning of a line.  So the following:

  Signed-off-by: Foo Bar <foo@bar.com>

should not trigger.
