Update misc/py-anita from 1.15 to 1.17.  Changes:

Update the discussion of Linux KVM virtualization compatibility in the
BUGS section, noting the --qemu-args -no-kvm-irqchip workaround and
including a reference to PR 44069.

New command line option "--sets".

Add a rudimentary INSTALL file.

The "misc" set is now installed by default, as it is required for
the ATF XML DTD, XSL files, and style sheets.

The "test" command now exports the raw and XML format ATF output
to the host, along with some auxiliary files needed for further
processing of the XML output.

Add support for FreeBSD hosts, from Kurt Lidl.
