  Acceptance tests: work around socket dir

Change 32558ce7a4 introduced specific directories for the socket dir
when using python/qemu/machine.py:QEMUMachine.  iotests probably
didn't catch the condition that two simultaneous QEMUMachine
instances, without manually set temporary or socket dirs would clash.

Having two QEMUMachine instances is a condition expected for many
acceptance tests, and it's already used by the migration tests.

  Python libs: close console sockets before shutting down the VMs

Currently, the console socket on QEMUMachine is closed after the QMP
command to gracefully exit QEMU is executed.  Because of a possible
deadlock (QEMU waiting for the socket to become writable) let's close
the console socket earlier.

  tests/boot_linux_console: Add a test for the Raspberry Pi 2

Similar to the x86_64/pc test, it boots a Linux kernel on a raspi2
board and verify the serial is working.

The kernel image and DeviceTree blob are built by the Raspbian
project (based on Debian):
https://www.raspbian.org/RaspbianImages
as recommended by the Raspberry Pi project:
https://www.raspberrypi.org/downloads/raspbian/

If ARM is a target being built, "make check-acceptance" will
automatically include this test by the use of the "arch:arm" tags.

Alternatively, this test can be run using:

    $ avocado run -t arch:arm tests/acceptance
    $ avocado run -t machine:raspi2 tests/acceptance

  tests/boot_linux_console: Run BusyBox on 5KEc 64-bit cpu

This tests boots a Linux kernel on a Malta machine up to a
busybox shell on the serial console. Few commands are executed
before halting the machine (via reboot).

We use the Fedora 24 kernel extracted from the image at:
