clean up smbios_set_defaults() which is reused by legacy
and non legacy machines from being aware of 'legacy' notion
and need to turn it off. And push legacy handling up to
PC machine code where it's relevant.

PS: I've moved/kept legacy smbios_entries to smbios_get_tables()
but it at least is not visible to API users. To get rid of it
as well, it would be necessary to change how '-smbios' CLI
option is processed. Which is done later in the series.

with this patch legacy tables build is moved to fw_cfg_build_smbios(),
however at this point QEMU still has option processing that fills
both new and legacy smbios_entries blobs.
this hunk cleanups not needed blob smbios_entries when building
modern tables, and smbios_get_table_legacy() has a corresponding
smbios_tables cleanup since modern is not needed there.
[7/19] removes this in favor of a single blob.

Yes the naming is confusing! There is smbios_entries and then there is smbios_tables. The former is only for legacy as the comment above smbios_add_field() says.
