Update OCaml requires/provides to ignore cmxs

OCaml cmxs files are static libraries, which can be loaded at runtime
via the Dynlink module. They apparently do not provide any useful
runtime dependency information to be stored into the packages
Provides/Requires list. Therefore just skip them.

Adjust attr, remove extension and ELF magic
Adjust ocamldeps, do nothing with cmxs files.
