Fix sepolicy-analyze libc++.so loading issue w/CTS.

Addresses the following error when running CTS on master:
junit.framework.AssertionFailedError: The following errors were encountered when validating the SELinuxneverallow rule:
neverallow { appdomain -bluetooth } self:capability *;
/tmp/SELinuxHostTest5593810182495331783.tmp: error while loading shared libraries: libc++.so: cannot open shared object file: No such file or directory

Also indicate that none of the sepolicy tools need c++ std lib.
