checkpatch: allow copyright statements > 80 columns

Exempt copyright statements from the 80 column rule as line-splitting or
other kinds of work-arounds decrease readability in diffs.  Identify the
copyright statement by looking for '+/* Copyright (c)', case-insensitive,
at the beginning of the line.
