pe-layout sensitivity of BGCEXP_LNDATM_CNPRDCTC tests

SMS_Ln5.ne30pg2_r05_EC30to60E2r2.BGCEXP_LNDATM_CNPRDCTC_1850 and SMS_Ln5.ne30pg2_r05_EC30to60E2r2.BGCEXP_LNDATM_CNPRDCTC_20TR tests appear to be sensitive PE-layout changes.

Tests on chrysalis created specifying --pesfile config_pes_tests.xml produced different results from tests not specifying --pesfile. The former uses P128x2 (with threading), while the latter uses staggered 22-node layout without threading.

The difference could be simply due to build with SMP or not.

Yes we already know that compiling with and without openmp produces bfb differences.
