use the pager like the other tools.

f37a291c52 perf_counter tools: Add more warnings and fix/annotate them 
Enable -Wextra. This found a few real bugs plus a number
of signed/unsigned type mismatches/uncleanlinesses. It
also required a few annotations

All things considered it was still worth it so lets try with
this enabled for now.

864709302a perf_counter tools: Move from Documentation/perf_counter/ to tools/perf/ 
Several people have suggested that 'perf' has become a full-fledged
tool that should be moved out of Documentation/. Move it to the
(new) tools/ directory.
