[PATCH] Avoid broken Solaris tr

[Ben Walton <bdwalton@gmail.com>]

Solaris' tr (both /usr/bin/ and /usr/xpg4/bin) fail to handle the case
where the first argument is a multi-character set and the second is a
single null character. Use perl to perform these substitutions
instead. Now that we're using perl for the transliteration, we might
as well replace the sed invocations with it too.

We make this change globally in t0008-ignores instead of just for the
cases where it matters in order to maintain consistency.
