Add nix-run and myEnvRun

This adds nix-run, which is a thin wrapper around nix-build.
nix-run calls nix-build, and then executes the resulting build.
If no executable artifact is built, nix-runs outputs an error
message.

myEnvRun calls myEnvFun and builds a script that directly runs
the load-env-* script.

Together, nix-run and myEnvRun allows you to set up an environment
that can be loaded in this way:

  envs.nix:
    {
      gcc = myEnvRun {
        name = "gcc";
        buildInputs = [ gcc ];
      };
    }

  $ nix-run -A gcc envs.nix

You end up directly in your environment without having to do
nix-env -i. You will always have a fresh environment and you
don't have to pollute you profile with a lot of env packages.

zfs: Fix libblkid detection (backport from upstream)

This fixes issues with importing ZFS pools, such as when the ZFS device is a
partition that covers the end of the disk.

See: https://github.com/zfsonlinux/zfs/issues/1684
zfs: Don't look for devices only in /dev

If we don't give out a directory to 'zpool import', it will use libblkid
to automatically find all existing ZFS devices.
zfs: Fix minor filesystem corruption with gcc 4.8

It turns out that some of gcc 4.8's aggressive optimizations may
cause minor filesystem corruption in ZFS. To fix it, a patch was
cherry-picked from the upstream's git tree.

See: https://github.com/zfsonlinux/zfs/pull/2051
