Do not ignore inspector_protocol and binutils directories

third_party/inspector_protocol is tracked in git and ignoring it causes
problems if the tree is copied to another git repository (e.g. Node.js)
Similarly, third_party/binutils has some files checked in. This adds a
.gitignore file in this directory (same as Chromium).
