lsm: CONFIG_LSM can depend on CONFIG_SECURITY

[ Upstream commit 54d94c4 ]

When CONFIG_SECURITY is not set, CONFIG_LSM (builtin_lsm_order) does
not need to be visible and settable since builtin_lsm_order is defined in
security.o, which is only built when CONFIG_SECURITY=y.

So make CONFIG_LSM depend on CONFIG_SECURITY.
