The libsndfile.so.1(libsndfile.so.1.0) provide was not generated
by find_provides due to a bug in find_provides (the symbol version
matches the soname). Just manually add it, as the find-requires
will pick up this name.

This broke the dependency tracking

This is a regular build of mesa but its put inside
/usr/lib/GL, with symlinks from /usr/lib so that it can easily be
switched out.
