selinux: Fix send_sigiotask hook 

The CRED patch incorrectly converted the SELinux send_sigiotask hook to
use the current task SID rather than the target task SID in its
permission check, yielding the wrong permission check.  This fixes the
hook function.  Detected by the ltp selinux testsuite and confirmed to
correct the test failure.
