 * 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.
