fix: TEST_PRINTF(): printing 64-bit hex numbers or pointers

[cmachida]

Hi there,

Thank you for the Unity project!!

We have a UNITY_SUPPORT_64 system and noticed that %llu works fine, but %llx and %p still print out 32 bits.
Can this patch be applied, or something better be applied to address this issue?

Thanks,
Curtis Machida
