dev-util/rt-tests: A collection of latency testing tools (new package)

rt-tests contains a set of programs that test and measure various components of
real-time kernel behavior, such as timer latency, signal latency and the
functioning of priority-inheritance mutexes. Additionally it contains hackbench,
a program to generate work for the scheduler.
