perf timechart: Add a process filter

During the Kernel Summit demo of perf/ftrace/timechart, there
was a feature request to have a process filter for timechart so
that you can zoom into one or a few processes that you are
really interested in.

This patch adds basic support for this feature, the -p
(--process) option now can select a PID or a process name to be
shown. Multiple -p options are allowed, and the combined set
will be included in the output.
