util/lint/checkpatch: Decrease commit message line length limit to 72 

Currently, `checkpatch.pl`, imported from the Linux project, checks for
75 characters per line [2]:

> 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.

But Gerrit’s Web interface and its commit hooks use with 72 characters
per line [2]:

    remote: commit 35bb56d: warning: too many message lines longer than 72 characters; manually wrap lines
    remote:
    remote: SUCCESS
    remote:
    remote:   https://review.coreboot.org/c/coreboot/+/60004 [DO NOT SUBMIT] Gerrit commit msg line length test [NEW]

So, decrease the suggested length from 75 to 72 characters per line.
