Summary:
On most hosts we were running shell commands with an empty environment.
The only exception was windows, which was inheriting the host enviroment
mostly by accident.
Running the commands in an empty environment does not sound like a
sensible default, so this patch changes Host::RunShellCommand to inherit
the host environment. This impacts both commands run via
SBPlatform::Run (in case of host platforms), as well as the "platform
shell" CLI command.
