[fuchsia][log] no longer force all logs klog

sysmgr now always provides std{out,err} and sends them to the kernel log, so
this change has little side effect for the persistent services it was
originally written for. This change does however fix UX issues for tools such
as amber_ctl that are run from shells.

Test: manually verified that netstack and amber logs are still visible in klog
