perf tools: Allow shuffling the build tests
Those tests take a long time and sometimes we stop it, so allow randomly
shuffling the tests so that we have a better chance of running more of
them in partial 'make build-test' runs.
Using it just on the 'build-test' target, i.e.:
make -C tools/perf build-test
Is equivalent to:
make SHUF=1 -C tools/perf -f tests/make
