[Tarantool-patches] [PATCH v1] build: fix build after commit 7b443650

["Alexander V. Tikhonov" <avtikhon@tarantool.org>]

Found that some package builds failed on the mistake in CMakeLists.txt
file, the failed packages and test builds were:
- CentOS 6
- CentOS 7
- Ubuntu 14.04
and static build based on Dockerfile.
The core of the issue appeared to be single backslash instead of double
at the comment in CMakeLists.txt file, which should pass the cmake
syntax rules.

Follow up #3308
