checkpatch: use utf-8 match for spell checking

The current code that checks for misspelling verifies, in a more complex regex, if $rawline matches [^\w]($misspellings)[^\w] Being $rawline a byte-string, a utf-8 character in $rawline can match the non-word-char [^\w]. E.g.: ./scripts/checkpatch.pl --git 81c2f059ab9 WARNING: 'ment' may be misspelled - perhaps 'meant'? #36: FILE: MAINTAINERS:14360: +M: Clément Léger <clement.leger@bootlin.com> ^^^^ Use a utf-8 version of $rawline for spell checking.
