   Testing sending invalid signals to sigdelset().
   After invalid signal sent, sigdelset() should return -1 and set
   errno to indicate the error.
   Test steps:
   1)  Initialize a full signal set.
   2)  Remove the invalid signal from the full signal set.
   3)  Verify that -1 is returned, the invalid signal is not a member of
       the signal set, and errno is set to indicate the error.
