   Test that sigdelset() will remove signo to the set signal set.
   Test steps:
   1)  Initialize an empty or full signal set.
	--> if argv[1] = 0, empty
	--> if argv[1] = 1, full
   2)  Add the SIGALRM signal to the empty signal set.
   3)  Verify that SIGALRM is a member of the signal set.
   4)  Remove the SIGALRM signal from the signal set.
   5)  Verify that SIGALRM is not a member of the signal set.
