Move to using tools/include/ instead.

We define init_utsname() as static but not inline, resulting
in a warning for every source file that includes lockdep.h but
doesn't call it.
Since it is only used by lockdep.c, define it in there.

__lock_pin_lock() now calls prandom_u32() which is not defined in
liblockdep. __lock_pin_lock() and its caller lock_pin_lock() are dead
code in liblockdep, but we still need to provide a definition of
prandom_u32() in case lazy binding is disabled.

The following upstream commit:
4a389810bc3c ("kernel/locking/lockdep.c: convert hash tables to hlists")
broke the tools/lib/lockdep build. Add trivial RCU wrappers to fix it.
These wrappers should probably be moved into their own header file.

kernel/locking/lockdep.c deals with validating locking scenarios for
various architectures supported by the kernel. There isn't
anything kernel specific going on in lockdep, and when we
compare userspace to other architectures that don't have to deal
with irqs such as s390, they become all too similar.
We wrap kernel/locking/lockdep.c and include/linux/lockdep.h with
several headers which allow us to build and use lockdep from
userspace. We don't touch the kernel code itself which means
that any work done on lockdep in the kernel will automatically
benefit userspace lockdep as well!
