marcel 52fb831b82 Move the inclusion of libdisk.h from sysinstall.h to the source files 
that actually need it. This makes it easier for a platform porter to
find the files that may need tweaking to support whatever MD specific
partitioning is needed. It also helps to prevent that the libdisk API
gets exposed and/or used where it's not needed.
