CI: Speed up Valgrind job by using --trace-children-skip-by-arg=...

This addresses the issue I mentioned in
6c095a98fbec70b790253a663173ecdb669108c4 and speeds up the Valgrind
job a bit, because non-xz tools aren't run unnecessarily with
Valgrind by the script tests.

(cherry picked from commit 7e99856f66c07852c4e0de7aa01951e9147d86b0)
