[roll] Roll fuchsia [rbe] Force relative path to avoid PATH search
This doesn't require local execution to have . in its PATH.
Without this might see an reclient error like:
```
E0224 15:44:58.549842 4013643 server.go:318] 40cedb2c-1dc0-4c35-a44a-f9a9bd2a6f27: Execution failed with &{ExitCode:35 Status:LocalErrorResultStatus Err:exec: "spawn_test_target.wrap.sh": executable file not found in $PATH}
```
because the named wrapper is in '.' (not necessarily included in PATH).

This repository contains Fuchsia's Global Integration manifest files.
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 via the IRC channel #fuchsia on Freenode.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
