[kvm-unit-tests PATCH v2 1/2] x86: Make cet and lam tests KVM-only

[Xiaoyao Li <xiaoyao.li@intel.com>]

Passing "-enable-kvm" in qemu_params forces tests to run with kvm
accelerator.  This leads cet and lam tests to run with kvm accelerator
silently without any warning even when "ACCEL=tcg" is passed.  Change to
require "accel = kvm" for cet and lam tests so that they can be skipped:

  SKIP cet (kvm only, but ACCEL=tcg)
  SKIP lam (kvm only, but ACCEL=tcg)

when "ACCEL=tcg" is passed.

As a bouns, removing the use of "-enable-kvm" will allow pass $ACCEL and
$ACCEL_PROPS to the standalone "-accel" QEMU parameter, since QEMU
translates "-enable-kvm" to "-machine accel=kvm", which is not
compatbile with "-accel" parameter:

  qemu: The -accel and "-machine accel=" options are incompatible
