nixos: Add option services.cron.cronFiles

This allows you to configure extra files that should be appended to your
crontab. Implemented by writing to /etc/crontab when the cron service starts.
Would be nicer to use a cron that supports /etc/cron.d but that would require
us to patch vixie-cron.

chromium: Update all channels to latest versions.

With this commit, the following new upstream versions are introduced:

stable: 37.0.2062.94 -> 37.0.2062.120
beta:   38.0.2125.24 -> 38.0.2125.101
dev:    39.0.2138.3  -> 39.0.2171.7

All channels built fine on my machine and were tested against a few
sites.

The missing_alg_import.patch now is no longer needed for version 39, so
we're not applying it there anymore.

chromium: Add WideVine content decryption plugin.

Seems to be needed in order to view Netflix content, but this only pulls
in the proprietary plugin and doesn't yet compile Chromium with support
for it, so this is only in preparation for the bright and shiny future
(where we all have rootkits implanted in our body).

Of course, this plugin is disabled by default as well as all the other
proprietary plugins.

For the plugin derivation, we now do the checkPhase _after_ the
installPhase, to make sure we also detect RPATHs pointing to the plugin
directory itself, because the shared object files only exist after the
installPhase.
