fuchsia: Add dependency on //headless to get headless_shell target

This lets gn generate build files that contain headless_shell as a
target, but there's still lots of porting to be done to get it to
actually build.

Dependencies on crash reporting are excluded, as it is expected
that a shipping product would rely on the Fuchsia system crash
reporter, so Chrome itself does not need a separate one.
