[PATCH] selinux: inherit /proc/self/attr/keycreate across fork

Update SELinux to cause the keycreate process attribute held in
/proc/self/attr/keycreate to be inherited across a fork and reset upon
execve.  This is consistent with the handling of the other process
attributes provided by SELinux and also makes it simpler to adapt logon
programs to properly handle the keycreate attribute.
