smbios: Simplify reporting of unknown values

If a value is not valid during the DT or SYSINFO parsing,  we explicitly
set that to "Unknown Product" and "Unknown" for the product and
manufacturer respectively.  It's cleaner if we move the checks insisde
smbios_add_prop_si() and provide an alternative string in case the
primary is NULL or empty

While at it make smbios_add_prop_si() add a string directly if the prop
node is NULL and replace smbios_add_string() calls with
smbios_add_prop_si(ctx, NULL, ....)
