futility/updater_dut: Extend property type from int to int64_t

Some property getter functions such as dut_get_tpm_fwver() use -1 as the
error return value. In order to support properties of uint32_t type
(such as SKU ID), change the property type from 'int' to 'int64_t'. Add
typedef 'dut_property_t' for that type.
