Packages build for opkg typically strip these out of the package,
because they take up space and have little use on the sort of devices
opkg is targetting. You'll probably have to recompile the package
yourself to include the required bits.
Why are you looking to install python-cffi directly, though? AFAIK,
openwrt provides a python-cffi packages already.

non-Python dependency of cffi.
Try something like "opkg install libffi-dev" or similar.

or google around to find the source code of libffi and try to compile
it manually.
A bientôt,
