Update open-vm-tools to 10.2.5-8068406

The currently bundled versions of open-vm-tools has an issue where only
16 IPs are going to be reported to the vmware hypervisor, and the link
local IP addresses of veth* NICs are included.

The end result of this is that if you start up a large compose file, the
VM's own IP will be pushed out of the reported guest IPs list, and
commands such as `docker-machine env` and `docker-machine ip` will hang.

See vmware/open-vm-tools#100
