checkpatch, SubmittingPatches: suggest line wrapping commit messages at 75 columns

Browse Source 
Commit messages lines are sometimes overly long.

Suggest line wrapping at 75 columns so the default git commit log
indentation of 4 plus the commit message text still fits on an 80 column
screen.

Add a checkpatch test for long commit messages lines too.
