[tools 1/2] testbot/SetWinLocale: Add an option to change the locale of VMs.

[Francois Gouget]

The --vm ensures the right TestAgent connection parameters will be used
to connect to the specified VM.

This partially reverts commit 206c7478dcb4 but with some important
differences:
- It does not parse the VM name to infer the locale to be used. Here
  --vm is purely a way to specify how to connect to that machine's
  TestAgentd server.
- It does not add back the options for 'refreshing' snapshots, or 
  creating new VMs for the specified locales. Those were not used and 
  are not coming back.
