Just propagate it as SLAPOS_TEST_LOG_DIRECTORY, then tests (running with

erp5_demo_maxma_rule: Add depend on erp5_accounting as it uses AccountingTransactionRootSimulationRule Document migrated from FS (a0c2b666).

This fixes CodingStyleTest tests.

erp5_simulation: Move Solver-related Python Scripts not used in erp5_base to erp5_simulation (a7d6edba).

This fixes test_SkinCodingStyle for erp5_base: 'Wrong prefix Solver for python script
