redhat: Remove parallel_xz.sh
The parallel_xz.sh script is no longer used. It is defined as Source22 but is never
called. The script was removed from execution in ark commit
e60c3381ad10 ("Temporarily backout parallel xz script") and never put back into execution.
A quick test doesn't show a benefit of using parallel_xz.sh so it can be safely removed.
Remove the unused parallel_xz.sh script.
Additional fix: The comment line is a remnant of configuring -j for
parallel_xz.sh and can also be removed.
