Subject: [PATCH] LSM: SafeSetID: 'depend' on CONFIG_SECURITY

From: Micah Morton <mortonm@...omium.org>

This patch changes the Kconfig file for the SafeSetID LSM to depend on
CONFIG_SECURITY as well as select CONFIG_SECURITYFS, since the policies
for the LSM are configured through writing to securityfs.
