Currently checkpatch warns us for long lines in commits even for
signature tag lines.
Generally these lines exceed the 75-character limit because of:
1) long names and long email address
2) some comments on scoped review and acknowledgement, i.e., for a
dedicated pointer on what was reported by the identity in 'Reported-by'
3) some additional comments on CC: stable@vger.org tags
Exclude signature tag lines from this class of warning.
There were 1896 COMMIT_LOG_LONG_LINE warnings in v5.6..v5.8 before this
patch application and 1879 afterwards.
A quick manual check found all the dropped warnings related to signature
tags.

Changes in v2:
modify commit message: remove specific commit example, add cause of the warning instead
Changes in v3:
modify commit message: minor english fix; remove difference count, add relative counts instead
