[PATCH] svnadmin: Print LOCK_PATH's correctly.

Patch + log message attached. It changes the expected output, and I'm not
sure how strictly compatible we want to be about that, hence posting here
first.

If I don't hear anything I'll go ahead and commit.

(It seems that the code being changed is passing an APR-encoded path to
a printing function that expects a UTF-8 argument? This might even be
user-visible as mangled output in non-UTF-8 environments, I suppose,
but I don't have such an environment to test with.)

Cheers,

Daniel
