chromium: Update dev and beta channels.

So, chromium 25 is now stable, so we really need to get the build fixed on Hydra
as soon as possible. And let's hope without nasty workarounds.

This commits updates dev and beta channels to version 26.0.1410.12, because
version 27.0.1423.0 seems to be unavailable right now. Build is running
successfully on my machine, and the browser works as well on the sites I usually
visit.

Revert "chromium: Force -fno-stack-protector..."

This reverts commit b7cbb4da11fb409d597df473d480c51fa0d11536.

The main reason behind this - apart from looking ugly - is that it didn't really
solve anything, see:

http://hydra.nixos.org/build/4198299

So, we need a different and less hacky approach...

chromium: Add /dev/null to patches list.

This is needed in order to ensure that the postPatch hook is executed, which is
not when the patches list is empty.

It is fixed by 82f94df719fe9fe5a861eafb575ccb1f8b5b5efb in stdenv-updates.
So as soon as the branch gets merged, we can get rid of this hack as well.

chromium: Update stable channel to v25.0.1364.97.

So, after searching for days in the wrong spot, eventually discovering that
postPatch isn't run on Hydra, we're now set to move forward to version 25, YAY!

Build has been tested locally (not that this would mean anything for Hydra, as
we've seen) and the output has been actively used for browsing by me :-)

chromium: Remove version 24 specific stuff.

This gets rid of the patch for newer pulseaudio library versions.

In addition, we now have protobuf and pciutils in default dependencies, as those
are required (or better: optional, but recommended and thus activated by the
default gyp options) by versions >= 25.

Also, we now no longer depend on libpng, but I'm not dropping this, as we want
to get back to libpng from nixpkgs again 'real soon'.

The stack-protector flag is now disabled by default accross all versions, and
probably didn't hurt back in version 24, but at least we're now no longer add it
dependant on a particular version.

And those pesky post/onlyXX version booleans are now pre/postXX, to ensure
better clarity.
