dev-lang/teyjus: Unbundle ocaml inc files, require ocaml[ocamlopt]

Fix 749996, unbundle old ocaml include files, and include the ocaml
system include files.

Fix 749996, remove the ocamlopt USE flag, and require
dev-lang/ocaml[ocamlopt].

Fix 726890, edit source/OMakefile to set CFLAGS and LDFLAGS.

Thanks to Toralf Forster and Agostino Sarubbo for reporting.
