trace_processor: extract actual argv0 from Chrome cmdline

Chrome child processes overwrites /proc/self/cmdline and replaces all
'\0' with ' ', which makes argv0 contain the full cmdline. This makes
the UI display incorrect and unusably long track group names.

This change adds a heuristics in the trace processor by looking for
"/chrome " in argv0 and extracts the actual argv0 for Chrome processes.
