UidStatsMapKey.java - uid U32 -> S32

The kernel is actually not consistent in whether uids & gids
are signed or unsigned, and neither is our Java code, which
also commonly uses just 'int' for uid.  In practice values
greater or equal to 2**31 often don't quite work right.
For example icmp sockets are enabled via a sysctl that
takes a minimum and maximum gid - and these are signed int32s.
