qemu: set smbios entries from fw_cfg

Qemu makes the guest uuid (qemu -uuid $uuid) available
to the guest via fw_cfg.  Other smbios fields can be
configured in qemu using the -smbios command line
switch (check the qemu manpage for details).

This patch adds coreboot support for this, so the
values provided by qemu will actually show up in the
smbios table.
