[roll] Roll fuchsia [rust] Remove unsupported target features

Apparently rustc doesn't recognize armv8-a or simd /shrug

We get a lot of this stdout spam:
```

Originally I thought this is necessary to get Rust auto vectorization to work.
In hindsight I'm not sure it's necessary to specify +simd.
The godbolt links here just say aarch64 which I guess is already implied?

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.
