Timezones in ubuntu based agent

[hardcorehead87]

We have tests running on the hosted linux preview agents that fail because timezones are missing.
When running a small test on the following docker images I get these results;

docker exec -it microsoft/vsts-agent:ubuntu-16.04-docker-1.12.1-standard

root@c7bad853c997:/var/temp# cat Program.cs
using System;

namespace temp
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Timezone test started.");
            var timezones = TimeZoneInfo.GetSystemTimeZones();
            foreach (var timeZoneInfo in timezones)
               Console.WriteLine(timeZoneInfo.Id);
            Console.WriteLine("Timezone test done.");
        }
    }
}
root@c7bad853c997:/var/temp# dotnet run
Timezone test started.
Timezone test done.

As stated in the following issue TZDATA has been removed from the upstream ubuntu image for space savings. This however causes parts of dotnet to malfunction because it depends on this data being available. The intended solution is to manually add the required package.
