.NET SDK installed to $INSTALL_DIR

Add it to your shell so 'dotnet' is on PATH:

  fish:
    set -gx DOTNET_ROOT $INSTALL_DIR
    fish_add_path $INSTALL_DIR

  bash / zsh:
    export DOTNET_ROOT="$INSTALL_DIR"
    export PATH="\$DOTNET_ROOT:\$PATH"

(The build script picks up ~/.dotnet automatically, so this is only needed for
running 'dotnet' by hand.)
