brillo sdk: Construct proper cache dir in SDK bootstrap
The SDK bootstrap has been an unknown checkout type and hence we've
always used "/tmp/chromeos-cache" as the cache directory. This CL adds
SDK bootstrap to the supported list. It will create a cache directory
under "chromite/sdk_checkouts/.cache".
