This patch adds support for the wait4 system call, and with that the wait3 call as well. The implementation is absolutely minimal: only user and system times of the exited child are returned (with all other rusage fields left zero), and there is no support for tracers. Still, this should cover the main use cases of wait4. Change-Id: I7a04589a8423a23990ab39aa38e85d535556743a
