MFC 306564: Expose kernel-only errno values if _WANT_KERNEL_ERRNO is defined.
The kernel uses a few negative errno values for internal conditions such as requesting a system call restart. Normally these errno values are not exposed to userland. However, kdump needs access to these values as some of then can be present in a ktrace system call return record. Previously kdump was defining _KERNEL to gain access to ehse values, but was then having to manually declare 'errno' (and doing it incorrectly). Now, kdump uses _WANT_KERNEL_ERRNO instead of _KERNEL and uses the system-provided declaration of errno.
