mb/google/glados/var/lars: Set SKU ID based on VPD
LARS has two variants, LARS and LILI, which are differentiated via
the customization_id field in the VPD. To make differentiation easier
outside of ChromeOS (ie, for Windows/Linux drivers), set the SKU ID
based on VPD so it can be easily read via SMBIOS.
Modeled after similar code in google/reef (snappy variant).
TEST=build/boot lili variant, verify sku1 populated in SMBIOS tables.
