tools: exclude deps/v8/tools from CodeQL scans

This will remove three of the four "A parse error occurred" issues
during JavaScript CodeQL scans. (The fourth occurrence is in our code
base, although it might be a false positive. Someone can figure that one
out sooner or later, but we certainly can bypass scanning V8 tools.)
