[pfff] export ast_php_simple.cmi

Summary:

CMF depends directly on this file, and it doesn't have an mli,
so we need to export this explicitly.

Test Plan:

  make install-findlib

[pfff] export findlib target for lang_php/analyze/matcher

Summary:

Same as the last couple; make this findlib-exportable so I can
link directly against the individual build products rather than
just one All of PFFF Blob.

Test Plan:

  make install-findlib # from various directories
