Subject: [refpolicy] [PATCH 1/1] Allow semodule to create symlink in semanage_store_t

With new userspace, trying to build a SELinux policy (and load it)
fails:

~# semodule -B
libsemanage.semanage_install_active: Unable to create sybolic link from
/etc/selinux/mcs/modules/active/policy.kern to
/etc/selinux/mcs/policy/policy.28 error code 0. (Permission denied).

AVC shows a denial for the semodule command, running as semanage_t,
trying to create a lnk_file in semanage_module_t.

Yes, it needs to be added. We have it in Fedora.
