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

Gerrit Web interface and commit hooks operate with 72 characters per
line [1]:

    remote:
    remote: SUCCESS
    remote:
    remote:   https://review.coreboot.org/c/coreboot/+/60004 [DO NOT SUBMIT] Gerrit commit msg line length test [NEW]

The Linux project checks for 75 characters per line. Update it to our
requirements.
