Lots of libselinux functions now map /sys/fs/selinux/status so add map
perms to other interfaces as well.
$ passwd user1
passwd: avc.c:73: avc_context_to_sid_raw: Assertion `avc_running'
failed.
Aborted
avc: denied { map } for pid=325 comm="passwd"
path="/sys/fs/selinux/status" dev="selinuxfs" ino=19 scontext=root:
sysadm_r:passwd_t tcontext=system_u:object_r:security_t tclass=file
permissive=1
