Subject: [PATCH 124/170] setsebool: support use of -P on SELinux-disabled
 hosts

As reported in #123, setsebool immediately exits with an error if
SELinux is disabled, preventing its use for setting boolean persistent
values.  In contrast, semanage boolean -m works on SELinux-disabled
hosts.  Change setsebool so that it can be used with the -P option
(persistent changes) even if SELinux is disabled.  In the SELinux-disabled
case, skip setting of active boolean values, but set the persistent value
in the policy store.  Policy reload is automatically disabled by libsemanage
when SELinux is disabled, so we only need to call semanage_set_reload()
if -N was used.

Fixes: https://github.com/SELinuxProject/selinux/issues/123
