[PATCH] KVM test: Add subtest smbios_table

[Lucas Meneghel Rodrigues <lmr@redhat.com>]

From: pradeep <psuriset@linux.vnet.ibm.com>

    Check smbios table :
    1) Boot a guest with smbios options
    2) verify if host bios options have been emulated,
       that is, the vendor, date and version options
       returned by dmidecode are the same on host and
       on guest.
