controllers/pids.sh: A few fixes

* Add executable flag to the pids.sh script

* Redirect stderr to stdout for kill pids_task2

* Fix the limit for third testcase:

  Since we start a pids_task1 which tries to do a fork and expects to
  succeed the limit must be lesser number of attached tasks - 2. It
  makes more sense to increase the parameter by two rather than
  decreasing it since the test 'pids.sh 3 1' fails because it tries to
  start -1 tasks. The runtest file is updated accordingly.
