[fint] Record ninja duration to artifacts

Some dashboards rely on the "build.ninja.fuchsia" step name to measure
the time that ninja takes to build fuchsia. I would like to simplify the
step name to "build.ninja", and ideally remove the dependency on
specific step names, which is fragile, and instead expose the ninja
duration as a build output property.

However, to get an accurate ninja duration we need to exclude `fint
build`'s post-processing steps (which may take up to ~30 seconds) from
the duration, hence the need to record the ninja duration within fint
and expose it to recipes.

Fuchsia

Pink + Purple == Fuchsia (a new operating system)

What is Fuchsia?

Fuchsia is a modular, capability-based operating system. Fuchsia runs on modern 64-bit Intel and ARM processors.

Fuchsia is an open source project with a code of conduct that we expect everyone who interacts with the project to respect.
