- Remove .gitmodules from .dockerignore so the build loop can discover
which directories to compile
- Add git to Dockerfile apt installs (needed for git config --file parsing)
- Gate git submodule update --init on .git presence, not .gitmodules;
the compile loop still runs in Docker since .gitmodules is now present
- hashcat skipped in Docker build loop since system hashcat is in PATH
