tests/acceptance: introduce arch parameter and attribute

Browse source 
It's useful to define the architecture that should be used in
situations such as:
 * the intended target of the QEMU binary to be used on tests
 * the architecture of code to be run within the QEMU binary, such
   as a kernel image or a full blown guest OS image

This commit introduces both a test parameter and a test instance
attribute, that will contain such a value.

Now, when the "arch" test parameter is given, it will influence the
selection of the default QEMU binary, if one is not given explicitly
by means of the "qemu_img" parameter.

The architecture can be used on different levels of the stack, e.g. by
the framework or by the test itself. At the framework level, it will
currently influence the selection of a QEMU binary (when one is not
explicitly given).
Tests are also free to use this attribute value, for their own needs.
A test may, for instance, use the same value when selecting the
architecture of a kernel or disk image to boot a VM with.
The ``arch`` attribute will be set to the test parameter of the same
name, and if one is not given explicitly, it will be set to ``None``.

This parameter has a direct relation with the ``arch`` attribute. If
