selftest/process_test: Fix output changing in new python version
On older versions apparently upon child termination due to SIGINT subprocess.poll() returned 1. On new python versions (such as 3.8.2), -2 is returned, according to documentation: A negative value -N indicates that the child was terminated by signal N (Unix only). Let's catch the SIGINT in the child process and exit with a known 42 value to fix different behavior. Change-Id: I7949ff2b435e91e890061e6840b0f411f8b0a817
