Ian Rogers 9a8dd2f24d perf test shell daemon: Make signal test less racy 
The daemon signal test sends signals and then expects files to be
written. It was observed on an Intel Alderlake that the signals were
sent too quickly leading to the 3 expected files not appearing.

To avoid this send the next signal only after the expected previous file
has appeared. To avoid an infinite loop the number of retries is
limited.
