[roll] Roll fuchsia [ffx] Fixed log check in strict mode

The handling of env vars in strict mode was incorrect (even after
fxr/1177196); one consequence was that the `log.enabled` compiled-in
default was being ignored, resulting in no logging occurring in
strict mode (which may actually be the right behavior, but it should
be explicit rather than dependent on a bug).
