[committed] Fix pr24174.sh

[Tom de Vries <tdevries@suse.de>]

Hi,

Test-case pr24174.sh contains:
...
grep "DWARF version 0 unhandled" dwz.err || true
...
where the intention is to check that the error message does not occur, but
which will pass regardless of what's in dwz.err.

Fix this by making sure the test fails if grep succeeds.

Committed to trunk.

Thanks,
- Tom
