Update perf_to_profile cli arguments to use flags. (#277)

Fixes #277

As perf_to_profile uses flags to parse its arguments, modify the call to perf_to_profile to use flags. Also pass the '-f' flag to overwrite the existing output profile file.
Redirect perf_to_profile's stdout/stderr to pprof's stdout/stderr.
