unix/Makefile: Only checkout libffi submodule when used. 

This moves the libffi submodule variable modifier inside of the if
statement where it is actually used so that the submodule will only be
checked out if it is actually being used.

A new DEPLIBS variable is also introduced to prevent building the libffi
submodule when not needed.
