capabilities: introduce security_capable_noaudit
Exactly like security_capable except don't audit any denials. This is for places where the kernel may make decisions about what to do if a task has a given capability, but which failing that capability is not a sign of a security policy violation. An example is checking if a task has CAP_SYS_ADMIN to lower it's likelyhood of being killed by the oom killer. This check is not a security violation if it is denied.
