[PATCH 1/3] pidns: remove now unused kill_proc function

[PATCH 1/3] pidns: remove now unused kill_proc function

[Pavel Emelyanov]

This function operated on a pid_t to kill a task, which is
no longer valid in a containerized system.

It has finally lost all its users and we can safely remove 
it from the tree.
