[PATCH v4 05/14] tools/lib/lockdep: add definition required for IRQ flag tracing

[Sasha Levin]

We are going to start building with CONFIG_TRACE_IRQFLAGS defined, so
let's wire up a few dummy variables in our task_struct.

This isn't needed in userspace, but due to some refactoring in
kernel-side lockdep it's easier to just wire it up and enable
CONFIG_TRACE_IRQFLAGS.
