apparmor: Remove SECURITY_APPARMOR_BOOTPARAM_VALUE
In preparation for removing CONFIG_DEFAULT_SECURITY, this removes the soon-to-be redundant SECURITY_APPARMOR_BOOTPARAM_VALUE. Since explicit ordering via CONFIG_LSM or "lsm=" will define whether an LSM is enabled or not, this CONFIG will become effectively ignored, so remove it. However, in order to stay backward-compatible with "security=apparmor", the enable variable defaults to true. Signed-off-by: Kees Cook <keescook@chromium.org>

- This option sets the default value for the kernel parameter
- 'apparmor', which allows AppArmor to be enabled or disabled
- at boot. If this option is set to 0 (zero), the AppArmor
- kernel parameter will default to 0, disabling AppArmor at

- kernel parameter will default to 1, enabling AppArmor at
