currently smbios_entry_add() preserves internally '-smbios type='
options but tables provided with '-smbios file=' are stored directly
into blob that eventually will be exposed to VM. And then later
QEMU adds default/'-smbios type' entries on top into the same blob.
It makes impossible to generate tables more than once, hence
'immutable' guard was used.
Make it possible to regenerate final blob by storing user provided
blobs into a dedicated area (usr_blobs) and then copy it when
composing final blob. Which also makes handling of -smbios
options consistent.
As side effect of this and previous commits there is no need to
generate legacy smbios_entries at the time options are parsed.
Instead compose smbios_entries on demand from usr_blobs like
it is done for non-legacy SMBIOS tables.
