[PATCH, testsuite]: Fix g++.dg/cilk-plus/CK/pr66326.cc FAILs

[Uros Bizjak]

We don't have to use cilk.h convenience header.

2015-11-09  Uros Bizjak  <ubiz...@gmail.com>

    * g++.dg/cilk-plus/CK/pr66326.cc: Do not include cilk.h.
    (main): Use _Cilk_spawn instead of cilk_spawn.

Tested on x86_64-linux-gnu and committed to mainline SVN.

Uros.
