Fixes for mvme68k tape and disk bootloaders.

fix argument parsing for disk and tape boot
        bootsd/boot.c
        bugcrt/m68k/Makefile.inc

tape boot was broken completely
        bootst/bootst.c

minor bug if bootloader was specific size (aout exec header is 0x20 not 0x30).
        writvid/wrtvid.c
