signal_handler_unregister() calls sigaction() with uninitializing
sa_flags in the struct sigaction.
Make sure sa_flags is always initialized in signal_handler_unregister()
by initializing the struct sigaction when declaring it.
Fixes: 73c55fa5ab55 (selftests/resctrl: Commonize the signal handler register/unregister for all tests)
