perf tools: Re-implement debug print function for linking python/perf.so
The python/perf.so python binding links a subset of objects. Re-implement 'verbose' and 'eprintf' so they (and consequently 'pr_debug') can be used in objects linked into pythin/perf.so. Note 'eprintf' must be re-implemented because the full version links the browser ui.
