Add SIGTHR (32) into list of signals permitted to be delivered to the

suid application. The problem is that Linux applications using old Linux
threads (pre-NPTL) use signal 32 (linux SIGRTMIN) for communication between
thread-processes. If such an linux application is installed suid or sgid
and security.bsd.conservative_signals=1 (default), then permission will be
denied to send such a signal and the application will freeze.

I believe the same will be true for native applications that use libthr,
since libthr uses SIGTHR for implementing conditional variables.
