[PATCH] process events connector: uid_t gid_t size issues 



The uid_t and gid_t fields appear to present a 32/64-bit userspace/kernel
problem for some archs.

This patch addresses the problem by fixing the size to the largest size for
uid_t/gid_t used in the kernel.  This preserves the total size of the event
structure while ensuring that the layouts of the ID change event match in
32 and 64-bit kernels and applications.
