Since asynchronous cancellation was removed from system by
commit c4dd57c300
Author: Ondřej Bílka <neleai@seznam.cz>
Date: Tue Jan 14 16:07:50 2014 +0100
Do not enable asynchronous cancellation in system. Fixes bug 14782.
We needlessly enabled thread cancellation before it was necessary.
As
only call that needs to be guarded is waitpid which is cancellation
point we could remove cancellation altogether.
we shouldn't check asynchronous cancellation on system.
[BZ #14782]
* tst-cancel-wrappers.sh: Remove system.
