tests: ls: cover quoting in the C.UTF-8 locale

The quoting characters and the printability of a multibyte character are
selected by the locale's codeset, not by its language, but no test
covered a locale that has a UTF-8 codeset and no language.

* tests/ls/quoting-utf8.sh: Check that in C.UTF-8 the locale/clocale
styles use the Unicode quotes and that literal/escape/shell-escape pass
a multibyte character through unaltered, whereas the plain C locale
octal-escapes it or replaces it with '?'.
