Avoid the following exception in the Identity test when the commit body
is empty:
Traceback (most recent call last):
File "zephyr/scripts/ci/check_compliance.py", line 2053, in main
n_fails = _main(args)
^^^^^^^^^^^
File "zephyr/scripts/ci/check_compliance.py", line 1988, in _main
test.run()
File "zephyr/scripts/ci/check_compliance.py", line 1459, in run
auth_name, auth_email, body = git(
^^^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: not enough values to unpack (expected 3, got 2)
This is triggered because ``%b`` represents the body of the commit
message, which can be empty if there's a single line in it, because the
first line is considered the title.
