Debian package: Add lsb-release to deps

The Debian package had a dependency on lsb-base [1], which doesn't
actually add any usable utilities, and is just a dependency required
by other lsb utils.  I believe the intention was to add a dependency
on 'lsb', which adds a bunch of (unnecessary) stuff.

Chrome uses lsb_release (in base/linux_util), so a direct dependency
on 'lsb-release' is added.  The RPM packge doesn't have this problem
because it depends on 'lsb', which pulls in lsb-release.

Add UMA metrics for the linux distro.

At this point, only included the distros that are currently supported
both by us and the distro maker. For example, Ubuntu 15.10 is not
included as it is no longer supported by Ubuntu.

If there is a large UNKNOWN usage, then we can try to add other popular
distros, such as Mint.

Unify if guards of GetLinuxWindowManager.

This comes from a review comment on http://crrev.com/2917483002. The
if guard on the function call to GetLinuxWindowManager is no longer
the same as the guard of the function definition.

This CL makes them the same again.

Detect more linux distros for metrics

We now correctly detect openSUSE Leap 42.2. The new versions of debian
and Fedora have also been added, along with (non-versioned) detection of
several popular distros which are not officially supported.

Given this is proposing to add a new string to UMA proto, please make sure to get chrome-privacy@ to sign off. (I suspect it should be fine, but we should get their sign off to make sure.)

We are scrapping the idea of adding a string to UMA proto. Will just use a histogram instead.

Update distro histogram

For supported distros, group the versions together so that we can more
easily see them together (include some spare ID range for each distro
too). Also add in a couple of future versions so that we don't have to
keep on updating the metrics.

Downside is that the old histogram values are deprecated and will take
a while to settle on the new values as newer versions roll out.

The list of distros should cover us for the next ~18 months.

Marking as fixed.
