fvp_mps2.jinja2: codecov: Use stdout-flush-wrapper.sh to run FVP

To workaround LAVA issue with capturing all of codecov output before
detecting EOF. The script was added previously to every docker image
produced for FVP packages. The usage of the wrapper is simple - use
it as the main executable in LAVA, and shift actual FVP executable
to wrapper's params.
