disk: part_dos: Move header to the main include directory

There are two different struct definitions for MBR partition table
entries: one in part_dos.h and a nearly identical one in part_efi.h.

To enable future consolidation of these two structures, move part_dos.h
to the main include directory. This makes it accessible from other parts
of the codebase, such as part_efi.h, and is the first step toward removing
the redundant definition.
