truncate: Fix integer portability issues

Browse Source 
* src/truncate.c: Explicitly convert from off_t to intmax_t
when printing numbers as they may be different types.
Also don't mix size_t and off_t types in operations as
the latter will be promoted to unsigned when these types
are the same size.
