find-provides.ksyms: set LC_ALL=C globally
    
    This makes the sort order a bit more predictable across various
    environments and also speeds up grep/sed/sort a bit as they no longer
    need to deal with non-trivial collations and multibyte sequences
    that may appear when some garbage is being parsed accidentally.
    
    * find-provides.ksyms: Add "export LC_ALL=C", remove "LC_ALL=C" from the
    specific calls.
