systemd-journal-flush: Require /var/log/journal rather than all filesystems

Backport: 14.04
Don't run hwclock if /dev/rtc doesn't exist

E.g. on EC2 instances.

chromium/source: Propagate system attribute.

The system attribute was already there in the function head of the
shared update helper but it actually wasn't used and thus later the
import of <nixpkgs> was done using builtins.currentSystem instead of the
system attribute inherited from the source derivation.

Now we correctly propagate the attribute, so that even when running a
64bit kernel you can run a 32bit Chromium with binary plugins.

chromium: Fix userns sandbox patch for version 36.

This fixes build for version 36, which i accidentally broke in commit
f6e31fadd80486cdd68e3ad3d7ae888aa81400b9.

The reason this happened, was that my Hydra didn't pick up the latest
commit and I actually tested and built the parent commit instead of the
update commit.

So, this commit is the real "builds fine, tested" for all channels.

Also, the sandbox client initalization has moved into
setuid_sandbox_client.cc, so we need to move the lookup of the
CHROMIUM_SANDBOX_BINARY_PATH environment variable there.

haskell-defaults.nix: let ghc-7.8.2 use the HEAD prefs for the time being

The whole notion of per-compiler HP-compliant environments has failed
anyway and I'll try to get rid of that ASAP, so it feels pointless to
configure that stuff for GHC 7.8.2 to begin with.

buildLocalCabal: allow cabalDrvArgs in buildLocalCabalWithArgs

allows to write neat expressions like (as we're still generating an
expression string):

```
{
  build = haskellPackages.buildLocalCabalWithArgs {
    inherit src name;
    cabalDrvArgs = {
      jailbreak = false;
      doCheck = false;
    };
  };
}
```

without resorting to weird kung-fu like darcs does:

```
darcs = haskellPackages.darcs.override {
  # A variant of the Darcs derivation that containts only the
  # executable and
  # thus has no dependencies on other Haskell packages.
  cabal = { mkDerivation = x: rec { final = haskellPackages.cabal.mkDerivation (self: (x final) // {
            isLibrary = false;
            configureFlags = "-f-library"; }); }.final;
          };
};
```

While here, move the `jailbreak = true;` as the default `cabalDrvArgs`
option.
