    stand: lua: module names should permit more
    
    The module entries should generally allow whatever is allowed as an
    env_var in the pattern table.  Notably, we're missing periods which
    would allow proper entries for .dtb files in loader.conf that don't need
    to specify a module_name entry for it.
    
    %d in this expression is actually redundant as %w is actually
    "all alphanumerics," but I've included it for now to match the env_var
    entry.  We should really remove it from both.
