Atari: fix fallout of change of INIT segment to 'bss' type

Browse Source 
The size of the load chunk was calculated incorrectly in exehdr.s
since the INIT segment is no longer being part of the file anymore.

While at it, change atari-cassette.cfg so that order of BSS and INIT
is the same as in the other configs. See 692f96409d4e809d8 why it was
in different order.
