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. Signed-off-by: Joe Richey <joerichey@google.com>
