smbios: catch zero-length strings
qemu may pass us zero-length strings for smbios fields, when starting
qemu this way ...
qemu -smbios type=1,version=,serial=test
... for example.
Today we don't specifically handle them and simply append them to the
string list. Therefore we get two string-terminating zeros in a row.
Result is that we by accident create a end-of-entry marker in the middle
of the entry.
Fix this by handling zero-length strings like non-present strings.
