Fixes EOS Anticheat setup showing up twice when starting The Finals.

Looks like on up to date Windows at least ImagePath in services' registry is always REG_EXPAND_SZ, even if service path doesn't have anything to expand. load_service_config() already minds the possibility of ImagePath having REG_EXPAND_SZ type (while should be fine with old prefixes having REG_SZ too).
