    Fix failure load locale template.
    
    The call to open_tmpl_archive was being passed a pointer to an
    object allocated on the stack. The object on the stack is not
    guaranteed to be initialized to zero so we need to minimally
    initialize `fname' in the struct locarhandle to ensure that
    open_tml_archive loads the default tempalte.
    
    This error was seen while debugging glibc installs in a qemu
    VM where it is more likely the stack pages were dirty. It has
    not been reported on non-VM systems.
