t7810: turn MB_REGEX check into a lazy prereq
In t7810 we verify whether the system has proper multibyte locale support by executing `test-tool regex` with a unicode character. When this check fails though we'll output an error that breaks the TAP format. Fix this issue by turning the logic into a lazy prerequisite.
