compel/ksigset: fix ksigaddset() UB and flushing mask
Found by Coverity error:
> CID 172193 (#1 of 1): Bad bit shift operation (BAD_SHIFT)
> 1. large_shift: In expression 1 << sig % 64, left shifting
> by more than 31 bits has undefined behavior. The shift amount,
> sig % 64, is as much as 63.
That is:
1. yes, UB
2. while adding a signal to mask, this has flushed all other
signals from mask.
