checkpatch: check utf-8 content from a commit log when it's missing from
charset
Check that a commit log doesn't contain UTF-8 when a mail header
explicitly defines a different charset, like
'Content-Type: text/plain; charset="us-ascii"'

Note: I slightly updated the regex for the "Content-Type" line check
since most of the time, the character set does not seem to be given
in quotes.
