[RFA] Remove KERNEL_U_ADDR from config/nm-nbsd.h

[RFA] Remove KERNEL_U_ADDR from config/nm-nbsd.h

The following patch removes the definition of KERNEL_U_ADDR from
the NetBSD native configs.

The reason for doing so: the definition is completely bogus.  NetBSD
has not used the U-area for process or core file debugging for many
many years, and the U-area isn't even double-mapped at a fixed address
anymore (i.e. there is no "u.").

In addition, pulling in <machine/vmparam.h> (for the USRSTACK definition)
on some targets causes a compilation error, since this file is not meant
to be included directly (or by userland at all!).

	* config/nm-nbsd.h (KERNEL_U_ADDR): Remove.
