vendorcode/google: support multiple SAR filenames

Using a fixed filename only allows for one SAR configuration to be
checked into CBFS. However, we have devices with shared firmware that
would desire separate SAR configurations. This change allows boards to
define a function to select one of multiple files stored in CBFS to be
used.
