tests: avoid false failure with unicode decomposed file systems

* tests/ls/dired.sh: macOS normalizes unicode characters to decomposed
(NFD) form when storing names in the file system, which breaks the
round-trip comparison employed by the test.  So instead use a character
which does not decompose; verified with:
  echo æ | uconv -f utf8 -t utf8 -x nfd | od -Ax -tx1z
