lzw: Count the size of the memory object by ptrdiff_t.
* src/lzw/ftzopen.h: The types of FT_LzwState->{buf_total,
stack_size} are changed from FT_UInt to FT_Offset, to match
with size_t, which is appropriate type for the object in
the memory buffer.
* src/lzw/ftzopen.c (ft_lzwstate_stack_grow): The types of
`old_size' and `new_size' are changed from FT_UInt to
FT_Offset, to match with size_t, which is appropriate type
for the object in the memory buffer.
