sysvinit-inittab: make TERM=vt102 on serial consoles

sysvinit-inittab: make TERM=vt102 on serial consoles

This makes more sense than the default TERM=linux (as set
by the linux kernel).
In addition, when using busybox init, it tries to achieve
the same (in a different way).

Both agetty, and busybox getty support the terminal type as
the last argument.
