[hurd,commited] hurd: rule out some mach headers when generating errno.h

[Samuel Thibault <samuel.thibault@ens-lyon.org>]

While mach/kern_return.h happens to pull mach/machine/kern_return.h,
mach/machine/boolean.h, and mach/machine/vm_types.h (and realpath-ing them
exposes the machine-specific machine symlink content), those headers do not
actually define anything machine-specific for the content of errno.h.

So we can just rule out these machine-specific from the dependency
comment.
