The `offset` argument to `mmap()` was computed with a direct cast from
pointer to `off_t`:
`(off_t)addr_hint - (off_t)map_base`
This causes a build failure when compiling since pointers and `off_t`
may differ in size on some platforms.
maps12.c: In function 'mmap_pages':
maps12.c:114:50: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
114 | filemap ? fd : -1, filemap ? ((off_t)addr_hint - (off_t)map_base) : 0);

maps12.c:114:69: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
114 | filemap ? fd : -1, filemap ? ((off_t)addr_hint - (off_t)map_base) : 0);
The fix in this patch is to cast both pointers to `intptr_t`,
perform the subtraction in that type, and then cast the result
back to `off_t`.
