Fix copying between the host and target signal sets for the case when
the target set is larger than the host set.
sigismember() returns 1 if the specified signal number is a member of
the specified signal set, but it can also return -1 if an error occurs
(e.g. an out of range signal number is specified). All non-zero values
would cause the signal to be added, so a comparison with 1 is added to
assure that only the signals which are really in the set get added to
the other set.
