Make it possible to pass in paths to opus_demo and opus_compare.

This patch lets you pass paths for opus_demo and opus_compare to the
run_vectors.sh script.

The motivation for this was for my aarch64 patches (forthcoming),
which I've been testing under qemu.  I want to run an emulated
opus_demo, but a native opus_compare, so the script completes in a
reasonable amount of time.
