    makeman.lua: Downgrade `make showconfig` error to warning
    
    The sh-based makeman silently ignored errors from `make showconfig`.
    Ignore errors also from makeman.lua (but emit a warning).
    
    We may want to revisit this in the future, but want makeman.lua to
    behave identically for now.
