chromium: Update beta and dev to latest versions.

beta: 34.0.1847.60 -> 35.0.1916.47 (builds fine, tested)
dev:  35.0.1883.0  -> 36.0.1941.0  (builds fine, tested)

For the new version 36, we needed to rebase our user namespaces sandbox
patch, because http://crbug.com/312380 is preparing for an upstream
implementation of the same functionality.

Also, we need to add ply and jinja2 to the depends on version 36. This
is done unconditionally, because I want to avoid cluttering up the
expressions with various versionOlder checks.

The sandbox binary had to be fixed as well and we no longer use system
zlib, as - who might have guessed it - it's a fast moving target at
Chromium as well.

chromium: Move update.sh back into the main path.

This is to ensure that nothing unexpected will be after the merge of the
refactoring branch, and also my own autoupdate machinery is expecting
this location, so there really is no reason to change it now.

chromium/common: Wrap lines to 80 characters.

Yes, it's just a comment and yes, it's so insignificant that everyone
would make a "O_o" face. But I'm getting annoyed by things like this.

Obviously that means no feature changes :-)
