Revert "[presubmit] use the correct path for third party libraries"

This reverts commit beaca8cf.

Reason for revert: Broke presubmit bot - https://ci.chromium.org/p/v8/builders/ci/V8%20Presubmit/2938

Note that the problem is not with this CL itself, but it uncovers some presubmit issue in Torque code. Until the latter is fixed, I'm reverting to unblock the tree.

Original change's description:
> [presubmit] use the correct path for third party libraries
> 
> This CL ensures that presubmit script checks Torque files in third_party
> dependencies.
