Hadrian: correctly Install libffi shared object files
In D5423 a hack to correctly install the libffi .so files is implemented. This is a quick and dirty solution to fix the hadrian build. Note [Hadrian: install libffi hack] from that patch and also issue #15837 (closed) have more details, but ultimately hadrian should not have a special case for libffi.
