John Johansen 524d8e1425 apparmor: disable showing the mode as part of a secid to secctx
Displaying the mode as part of the seectx takes up unnecessary memory,
makes it so we can't use refcounted secctx so we need to alloc/free on
every conversion from secid to secctx and introduces a space that
could be potentially mishandled by tooling.

Eg. In an audit record we get

  subj_type=firefix (enforce)

Having the mode reported is not necessary, and might even be confusing
eg. when writing an audit rule to match the above record field you
would use

  -F subj_type=firefox

ie. the mode is not included. AppArmor provides ways to find the mode
without reporting as part of the secctx. So disable this by default
before its use is wide spread and we can't. For now we add a sysctl
to control the behavior as we can't guarantee no one is using this.
