Set max line length in gfortran for free format to infinite (was default 132)

• Dirac did not compile with gfortran for me, because of this recent change:
  • All lines except Fortran comment lines in src/exacorr/talsh_1rdm_2rdm_ccsd_kernels.F90 longer than 132 char
  • 3437 > norm2_total = tensor_norm2(gamma%asym_oo)+tensor_norm2(gamma%asym_ov)+tensor_norm2(gamma%asym_vo)+tensor_norm2(gamma%asym_vv)
  • 3437 > length of line : 134
• I do not understand why the CI pipleline mpich-32 with gfortran passed ??
