patch 9.1.1678: Amiga: cannot handle large undo files

Problem: Amiga: cannot handle large undo files
Solution: Remove the existing restriction as it was only valid for
classic Amiga (Damien Lejay).

It seems that this block was only relevant for classic AmigaOS (< 32K
alloc limit). And it seems to no longer apply: AmigaOS 4.0 switched to
a slab allocator memory system.

closes: #18072

It might make things unneccessarly complicated, but AOS 4.x is only available
for ppc equipped machines. For m68k machines the latest AOS update was 3.2 by
Hyperion only recently AFAIR (funny that there where 3.5 and 3.9 by H&P in the
early 2000..).

Didn't really used my 2 1200er in the last 20 years or so, though.
