Revert "src, tools: add debug symbols for node internals"

This reverts commit 446c1ec.

Reverted for breaking `make test-v8`.  The "find all relevant system
headers" logic in `tools/gen-postmortem-metadata.py` needs more work.

Also reverts commit e46c3f7.
("tools: fix typo in gen-postmortem-metadata.py".)
