VirtualBox with hardening support requires the main binaries to be
setuid root. Using VBOX_WITH_RUNPATH, we ensure that the RPATHs are
pointing to the libexec directory and we also need to unset
VBOX_WITH_ORIGIN to make sure that the build system is actually setting
those RPATHs.
The hardened.patch implements two things:
* Set the binary directory to the setuid-wrappers dir so that
VboxSVC calls them instead of the binaries from the store path. The
reason behind this is because nothing in the Nix store can have the
setuid flag.
* Excempt /nix/store from the group permission check, because while it
is group-writeable indeed it also has the sticky bit set (and also
the whole store is mounted read-only on most NixOS systems), so we're
checking on that as well.
Right now, the hardened.patch uses /nix/store and /var/setuid-wrappers
directly, so someone would ever want to change those on a NixOS system,
please provide a patch to set those paths on build time. However, for
simplicity, it's best to do it when we _really_ need it.

Traversing the full source tree is unneccessary, because the calls are
only done within make files. Hence we only substitute make files now.

Thanks to @iElectric for the notification, although I'm not really sure
whether this will fix the following failed Hydra build:
http://hydra.nixos.org/build/17609086/nixlog/1/raw
The reason is that this failure doesn't happen on every build, but let's
see whether it will happen again now.

This is a response to 1fdefd5562.
We are already using bundled protobuf for the beta and dev channels and
it also breaks regularly with about every new Chromium release, so let's
use bundled protobuf for all channels now.

We now create Nix expressions within the plugin output path(s) which
then will be imported and incorporated into the wrapper. This makes it
easier for other plugins to provide configuration settings to the main
Chromium wrapper.
Of course, in order to allow for external plugins we need to allow
passing a list of plugins to the Chromium derivation, but right now we
keep it internal and only use it for things such as NaCl (as soon as we
support it, of course).
