[RootFS] Upgrade Ninja

[amontoison]

The version of Ninja in RootFS (1.9) is too old to handle the dependencies between Fortran modules.
We should upgrade it to the a version >= 1.11 next time that we regenerate RootFS.
If someone encounter issues during the compilation of Fortran packages with Meson, the following code in your build_tarballs.Jl could help:

 python3 -m pip install --user --upgrade ninja
cp /root/.local/bin/ninja /usr/bin/ninja

or

# Update Ninja
cp ${host_prefix}/bin/ninja /usr/bin/ninja
...
