[roll] Roll fuchsia [elf_runner] suppress log warnings on certain components

There are some ELF programs that upon exit, produce certain exit codes that
are "normal" part of operation. The most interesting of these from Fuchsia's
perspective is the sshd binary, which returns a 255 exit code when the client
hangs up unexpectedly (e.g. sending SIGINT to a running ssh process).

Due to how `ffx` interacts with the Target over ssh in a user-interactive mode,
it is commonplace for the user to SIGINT their locally running ffx processes
which SIGINT's the SSH process running on the Host, which causes misleading
logs on the Target, implying that sshd has had an error (when in-fact there is none).

Tests: Added unit tests. Also can do manual testing by:
Flash target with new elf_runner binary, run `ffx log --severity trace
--component klog` in one terminal. Then in another terminal run `ffx -c
ssh.controlmaster.mode='none' log`. Wait until output and then hit
Ctrl+C. Observe the trace log in the first console.

Integration

This repository contains Fuchsia's Global Integration manifest files.

Making changes

All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.

Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance in one of the communication channels documented at get involved.

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
$ jiri update

Third party

Third party projects should have their own subdirectory in ./third_party.
