Speed up "make test" (around 5 times).

Browse source 
The reason for the apparent slowness was that the "cpuid_tool" that
was being called from run_tests.py is actually a shell script - a
wrapper, installed by libtool. The script was heavy enough to cause
substantial overhead. Just bypassing it (by using the real
cpuid_tool binary) reduced "make test" running time from 4.1 to 0.7s
on my machine.

It is a bit hacky, though, so "make test-old" is retained, which
uses the old invocation.
