find-provides.ksyms: set LC_ALL=C globally

Browse Source 
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.
