fix(clang-tidy): install libomp-dev to prevent clang-diagnostic-error

[kenji-miyake]

Description

Without this, it causes the following error due to the -fopenmp option.

/usr/include/eigen3/Eigen/Core:70:10: error: 'omp.h' file not found [clang-diagnostic-error]
#include <omp.h>

LLVM OpenMP runtime - dev package

My test results in autowarefoundation/autoware_common#90.

Eigen/Core:

#if (defined _OPENMP) && (!defined EIGEN_DONT_PARALLELIZE)
  #define EIGEN_HAS_OPENMP
#endif

#ifdef EIGEN_HAS_OPENMP
#include <omp.h>
#endif

Without OpenMP (by unclearing _OPENMP):

I'll merge this since it's a small change and I've tested it.
