[PATCH 1/1] capabilities: use cap_task_prctl when !CONFIG_SECURITY

[Serge E . Hallyn]

capabilities-implement-per-process-securebits.patch introduced
cap_task_prctl() and moved the handling of capability-related
prctl into it.  So when !CONFIG_SECURITY, the default
security_task_prctl() needs to call cap_task_prctl() the way
other default hooks call capability helpers when they exist.

This fixes a slew of userspace breakages when
CONFIG_SECURITY=n.
