xenalyze: increase MAX_CPUS

On a large system xenalyze will refuse to process the trace file because it
has an hardcoded limit of 32 cpus.  The default of NR_CPUS in xen-unstable is
128. Increase the limit to match xen-unstable and also add an option to
override the macro with a gcc cmdline option.
