intptr_t and uintptr_t are not big enough types on 32-bit architectures when printing 64-bit values, resulting to the following incorrect diagnostic output:

Replace intptr_t and uintptr_t with intmax_t and uintmax_t, respectively. With this fix, the same test produces more usable diagnostic output:
# get_syscall_info.c:209:get_syscall_info:Expected exp_args[2] (3134324433) == info.entry.args[1] (18446744072548908753)

Ah nice, thanks!
