Previously append_seed_arg() just do fill in seed arg to dest cmd buffer, so rename the api name to fill_seed_arg(). Since fill_seed_arg() will be called in SOS VM path only, the param of bool vm_is_sos is not needed and will be replaced by dest buffer size. The seed_args[] which used by fill_seed_arg() is pre-defined as all-zero, so memset() is not needed in fill_seed_arg(), buffer pointer check and strncpy_s() are not needed also.
