KVM-test: And check the cpu vendor_id in physical_resources_check

Since we do not have a simple way to identify the vendor_id
in the Windows guests, this test is limited to linux guests
for now.

Changes from v4:
 - Add a default cpu model in case qemu can't get cpu model
   from host's /proc/cpuinfo.
 - Add checking cpu vendor id cmd for win guest.
 - Rollback the cmd for checking vendor id in linux to
   'grep vendor_id /proc/cpuinfo', to make this case can also
   work on the guest without 'lscpu' cmd, eg, RHEL5.

Changes from v3:
 - Use 'lscpu' to check cpu vendor id.

Changes from v2:
 - The default vendor of cpu64-rhel6, qemu64 is AuthenticAMD,
   change vendor id to "AuthenticAMD", to make guest can get
   correct cores, threads, sockets

Changes from v1:
1. limit customized vendor_id to Linux guests.
2. test vendor_id in physical_resources_check, rather than in a
new testcase.

KVM-Test: physical_resouces_check: Add sockets/cores/threads check

Add sockets, cores, threads number checking test

Changes from v5:
 - Get cpu topology info from vm.cpuinfo class directly.

Changes from v4:
 - Update the code for getting chk_cmd parameter in
   check_cpu_number() function
 - Give default value to chk_timeout.

Changes from v3:
 - Verify regex search result for cpu check, avoid list out of
   index error.

Changes from v2:
 - Putting actul checking steps into a sub-function called
   check_cpu_number
 - Update default values for sockets/cores/threads configuration,
   make them same as configs in kvm_vm file.

Changes from v1:
 - Change timeout to int(timeout)
 - Add timeout while checking cores, threads, sockets
