[PATCH v3 1/6] tools: add a userspace tools bug.h

["Luis R. Rodriguez" <mcgrof@kernel.org>]

This will be used later by the userspace linker-tables sandbox.
As a convenience, include bug.h on kernel.h -- this is not done
on upstream kernel.h, however most header files do include bug.h
eventually, if we were to only add the ones that need it we'd
need to copy a lot of headers to tools for the ony purpose of
includeing bug.h. This simplifies that.
