[yocto] [yocto-autobuilder][PATCH v2] enable use of kvm with qemux86*

[Bill Randle]

When used with corresponding oe-core patch, this will enable the use
of kvm when running qemux86* images on a x86* host that supports kvm.
On the same build machine, for an x86_64 testimage run, the with and
without times are:
  without kvm:
    core-image-sato-1.0-r0 do_testimage: Ran 43 tests in 728.726s
    core-image-sato-sdk-1.0-r0 do_testimage: Ran 52 tests in 1090.838s
  with kvm:
    core-image-sato-1.0-r0 do_testimage: Ran 43 tests in 60.255s
    core-image-sato-sdk-1.0-r0 do_testimage: Ran 52 tests in 71.719s
