Kees Cook 2dea756b48 Revert "exec: avoid RLIMIT_STACK races with prlimit()" ...

commit 779f4e1c6c upstream.

This reverts commit 04e35f4495.

SELinux runs with secureexec for all non-"noatsecure" domain transitions,
which means lots of processes end up hitting the stack hard-limit change
that was introduced in order to fix a race with prlimit(). That race fix
will need to be redesigned.
