Include correct type definition in .h files

Right now, cryptsetup makes an attempt to include the correct
definitions in all of its header files, allowing the headers to
compile regardless of the context in which they are included.

A few files were missed, this change fixes them by adding the minimal
set of #includes needed to get them to compile.
