[Toaster] [PATCH 4/4] toaster: run builds in pid namespace

[Ed Bartosh]

Used pid namespace for runbuilds process. As runbuilds becomes
an init(pid 1) in its pid namespace, killing it will result in
killing all processes in the pid namespace(children of runbuilds process).
This way is much more effective than using PIDs or even PGIDs as
it doesn't leave any processes running.
