New formula: stress 1.0.4

From the developer: "stress is a deliberately simple workload generator
for POSIX systems. It imposes a configurable amount of CPU, memory, I/O,
and disk stress on the system. It is written in C, and is free software
licensed under the GPLv2"

I created this formula because it serves a simple but specific purpose
and is regularly available on Linux *BSD system.
