One of the things that fp-stress does to stress the floating point context switching is send signals to the test threads it spawns. Currently we do this once per second but as suggested by Mark Rutland if we increase this we can improve the chances of triggering any issues with context switching the signal handling code. Do a quick change to increase the rate of signal delivery, trying to avoid excessive impact on emulated platforms, and a further change to mitigate the impact that this creates during startup.

Applied to arm64 (for-next/kselftest), thanks!
