tp: process.start_ts: accept explicit zero as the process' start time from procfs

The data from procfs normally has 10ms resolution, so early kernel
threads can legitimately have an age of zero. Hence distinguish
set-to-zero proto field from unset fields (as we'd see in traces without
age recording).

Perfetto - System profiling, app tracing and trace analysis

Perfetto is a production-grade open-source stack for performance instrumentation and trace analysis. It offers services and libraries and for recording system-level and app-level traces, native + java heap profiling, a library for analyzing traces using SQL and a web-based UI to visualize and explore multi-GB traces.

See https://perfetto.dev/docs or the /docs/ directory for documentation.
