[PATCH v4 0/8] Acceptance tests: boot Linux with KVM test

[Wainer dos Santos Moschetta <wainersm@redhat.com>]

This adds boot Linux tests for x86_64, aarch64, ppc64, and s390x
targets which, unlike others, enable the KVM acceleration. Likewise
it was added test cases for tcg.

It is introduced an infraestructure on avocado_qemu framework
so that:
a) simply tagging the test with `accel:kvm` (or `accel:tcg`) will
automatically set the corresponding '-accel' on the launched
QEMU;
b) test is canceled if the accelerator is not enabled on the QEMU
binary or not available in the host. In special, it checks if SMT
is disabled on POWER8.

The acceptance builder on Travis was changed too in order to make
the test run.

Changes v3 -> v4:
- Broke changes per-arch to ease the reviews. Resulting on
  patches 02, 03, 05, 06.
- The test for aarch64 now passes '-cpu max' and
  -M 'virt,gic-version=max'. (patch 03) [drjones]
- Added a fix to accel.kvm_available() so that it detects
  correctly the availability of kvm on ppc64le. (patch 05)
- The test for ppc64le now checks if SMT is enabled on
  POWER8 then skip.
