    Makefile: Provide way to ship livepatch test files
    
    In the toplevel Makefile, provide build-tests and install-tests
    targets which descend into xen/test.  (dist-tests is provided
    automatically by the pattern rule, as is the convention here.)
    
    We have to set BASEDIR ourselves, and use these curious runes, because
    the convention in Makefiles under xen/ is to "make -f Rules.mk" with
    BASEDIR set and to expect Rules.mk to reinvoke the per-directory
    Makefile.  (This is really very strange.)  Normally this invocation
    pattern is organised by the machinery in xen/Makefile (which sets
    BASEDIR) and Rules.mk, but we need to invoke it from outside that
    context.
    
    In theory it would be nice to have a pattern rule %-tests.  But this
    is not the style in the rest of the toplevel Makefile; and doing that
    might interfere with the dist-% pattern rule.
    
    None of this is invoked by default.  If install-tests or dist-tests is
    requested, the livepatches (the only current output from xen/tests)
    are shipped in DESTDIR/usr/lib/debug/xen-livepatch/.
    
    This allows CI systems such as osstest which are trying to consume
    this to arrange for the files to be built, and output, without them
    having to have special knowledge of the details of Xen's build system.
