Unbreak `sysutils/linuxfdisk' after r276737, which removed DIOCGDINFO once

and for all; the code in `sys_bsd.c' is already using working alternatives
DIOCGMEDIASIZE and DIOCGSECTORSIZE except in sys_bsd_getgeometry(), but it
returns -1 for me even on stable/8.  While here, clean up Makefile a bit.
