Update 'nix-upstream' sub-module; adjust build system, doc, and substituter.
* nix-upstream: Update sub-module.
* daemon.am (libutil_a_SOURCES): Add affinity.cc.
(libutil_headers): Add affinity.hh.
(libexec_PROGRAMS, nix_setuid_helper_SOURCES,
nix_setuid_helper_CPPFLAGS, nix_setuid_helper_LDADD): Remove.
* doc/guix.texi (Setting Up the Daemon): Remove paragraph about
'nix-setuid-helper'.
* guix/scripts/substitute-binary.scm (guix-substitute-binary): Exit 0 when
