Upgrade Docker binary for Linux to version >19.03.2

[deviantony]

In order to support Compose format 3.8

See #3036 for the Windows counterpart.

Reverted via #3210

This is causing issues with TLS enabled endpoints and Swarm stacks deployments.

It appears docker --tls -H my.env:2376 now forces tls validation in 19.03 whereas it was working with self signed certs in < 19.03

Using portainerci/portainer:develop with the docker 19.03.2 binary merged, gave me the following issue as deviantony mentioned above:

Steps to reproduce:

1. Add your agent enabled endpoint
2. Select this endpoint in the home view
3. Go to stacks view
4. Try to deploy a simple stack

version: '3'
services:
  test:
    image: nginx

5. Recieve following errors:
   Toast error in Portainer UI: Deployment error

Error from inspecting network request:
{"message":"unable to resolve docker endpoint: open /.docker/ca.pem: no such file or directory\n","details":"unable to resolve docker endpoint: open /.docker/ca.pem: no such file or directory\n"}
