[Tarantool-patches] [PATCH v1] build: fix unit tests build with lrt

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

After the commit 77fa45bd05f8cdd4c0f9bad85185ef5b61528d49
the unit tests builds failed like:

/opt/rh/devtoolset-6/root/usr/libexec/gcc/x86_64-redhat-linux/6.3.1/ld:
  ../../src/lib/core/libcore.a(fiber.c.o): undefined reference to symbol
  'clock_gettime@@GLIBC_2.2.5'
//lib64/librt.so.1: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
test/unit/CMakeFiles/cbus.test.dir/build.make:108: recipe for target
  'test/unit/cbus.test' failed
make[2]: *** [test/unit/cbus.test] Error 1

To fix it the rt library needed to be added like for unit tests builds.
Added -lrt to 25 builds from overall 60 at cmake file.

Close #4639
