selftests: timers: clocksource-switch: fix passing errors from child
[ Upstream commit 4d8f52ac5fa9eede7b7aa2f2d67c841d9eeb655f ]
The return value from system() is a waitpid-style integer. Do not return
it directly because with the implicit masking in exit() it will always
return 0. Access it with appropriate macros to really pass on errors.
