Fix datebase creation so it has a log with new OpenROAD

[donnie-j]

Quick hack to fix compatibility with OpenROAD from OpenLane 2.0.8.

Without this change, DFFRAM fails with:

[CRITICAL ODB-0001] No logger is installed in odb. [15:32:37] ERROR Subprocess had a non-zero exit. step.py:1308 [15:32:37] ERROR Last 3 line(s): step.py:1313 [WARNING ORD-0039] .openroad ignored with -python [CRITICAL ODB-0001] No logger is installed in odb.
