performance test support glibc preload test

The glibc preload tests sets up an ld.so.preload to emulate a loaded
system.   This directly affects the runtime of the jq performance test.
This is a test change to check speed of the system first with pigz and
adjust expected jq speed test threshold.

It should be noted that to perform the system check before the jq check,
we need to test with something that uses threads.   This is why pigz was
chosen over traditional gzip.
