tests: define PRI__[dux]64 macros to print __s64 and __u64 values

Browse Source 
Rather than cast every __u64 or __s64 before printing,
define printing helpers for those types directly.

This complements commit 1f3482bedad505a41caf1d61b3a4e7e09a2f4330.

* tests/tests.h (PRI__d64, PRI__u64, PRI__x64): New macros.

* The kernel used to define 64-bit types on 64-bit systems on a per-arch
* basis. Some architectures would use unsigned long and others would use
* unsigned long long. These types were exported as part of the
* kernel-userspace ABI and now must be maintained forever. This matches
* what the kernel exports for each architecture so we don't need to cast
* every printing of __u64 or __s64 to stdint types.
