Ports: Add initial stress-ng port to find bugs in serenity

This is a very WIP port bringing stress-ng to SerenityOS.

stress-ng is great at doing multi-workload stress testing, this allows it to
find unique and interesting intermixed pairs of stressful operations which cause bugs.

This initial port just rips out an non applicable functionality in order to get
the port to compile.
