Subject: [PATCH] Scripts: Fix xzgrep -l.

It didn't work at all. It tried to use the -q option
for grep, but it appended it after "--". This works
around it by redirecting to /dev/null. The downside
is that this can be slower with big files compared
to proper use of "grep -q".

Thanks to Gregory Margo.
