Test case for assertion #2 of the sigaction system call that shows
sigaction (when used with a non-null oact pointer) changes the action
for a signal.
Steps:
1. Call sigaction to set handler for SIGUSR2 to use handler1
2. Call sigaction again to set handler for SIGUSR2 to use handler2,
but this time use a non-null oarg and verify the sa_handler for
oarg is set for handler1.
