check-mailmap doc: note config options

Add a passing mention of the mailmap.file and mailmap.blob
configuration options. Before this addition a reader of the
"check-mailmap" manpage would have no idea that a custom map could be
specified, unless they'd happen to e.g. come across it in the "config"
manpage first.
