docker: the image carries tools/FakeRAM2.0

flow/scripts/memories/gen_memories.py runs tools/FakeRAM2.0/run.py,
found relative to itself. The image copies flow/ and tools/AutoTuner but
not tools/FakeRAM2.0, so every AUTO_MEMORIES flow run from the image
stops at the memories step:

    /usr/bin/python3: can't open file
    '/OpenROAD-flow-scripts/tools/FakeRAM2.0/run.py': [Errno 2] No such
    file or directory

No design in CI sets AUTO_MEMORIES today, so CI on master does not show
it; a PR that adds one fails there (asap7/cva6 in #4777).
