Comparing the current version with the version in sources list and
accidentally swapping the version arguments isn't going to get very far
because every new version that will come up will then be treated as "we
already have that version".
So we're now using versionOlder and also a check whether the version is
the *same* as the one in sources.nix.

No changes in functionality, but to make future source updates a bit
easier on the eyes when viewing the diff.

The update.sh shell script now is only a call to nix-build, which does
all the hard work of updating the Chromium source channels and the
plugins. It results in a store path with the new sources.nix that
replaces the already existing sources.nix.
Along the way, this has led to a quite massive workaround, which abuses
MD5 collisions to detect whether an URL is existing, because something
like builtins.tryEval (builtins.fetchurl url) unfortunately doesn't
work. Further explanations and implementation details are documented in
the actual implementation.
The drawback of this is that we don't have nice status messages anymore,
but on the upside we have a more robust generation of the sources.nix
file, which now also should work properly on missing upstream
sources/binaries.
This also makes it much easier to implement fetching non-GNU/Linux
versions of Chromium and we have all values from omahaproxy available as
an attribute set (see the csv2nix and channels attributes in the update
attribute).

As stated in the parent commit, the 32bit Chrome package is not
available upstream, so let's at least provide the SHA256 hash for the
64bit package.

Until now, if we have a failure to fetch either the 32bit Debian package
or the 64bit Debian package, neither of these will be put into
sources.nix.
Unfortunately the beta/dev channels do not have a 32bit Debian package,
so even though there is a 64bit Debian package available we don't get
plugins *at* *all*.
This also introduces a nicer error message rather than just failing with
an assertion in fetchurl because we did not provide url/urls.

Python has not been made optional due to the additional complexity of:
- python2 vs python3
- pync support on Darwin
Making Python support optional should be revisited at another time.
