tst_QDnsLookup: Use a different character from space in TXT multi

When in commit db15341d273730298ab5af03b59e9ea1cca782be I added support
for testing TXT, I used the space character to make it easy to
concatenate the records. Unfortunately, that means it's easy to false-
positive the test by creating one record with a single entry containing
a space instead of two entries.

So use the NULL character instead.
