[PULL 63/63] acpi/tests/avocado/bits: enable console logging from bits VM

["Michael S. Tsirkin" <mst@redhat.com>]

From: Ani Sinha <anisinha@redhat.com>

Console logs from the VM can be useful for debugging when things go wrong.
Other avocado tests enables them. This change enables console logging with the
following changes:
 - point to the newer bios bits image that actually enabled VM console.
 - change the bits test to drain the console logs from the VM and write the
   logs.
 - wait for SHUTDOWN event from QEMU so that console logs can be drained out
   of the socket before it is closed as a part of vm.wait().

Additionally, following two cosmetic changes have been made:
 - Removed VM QEMU command line logging as avocado framework already logs it.
   This is a minor cleanup along the way.
 - Update my email to my work email in the avocado acpi bios bits test.
