Include files required for cipd_bin_setup to recipe bundle

https://crrev.com/c/3674982 caused compile step failures finding depot_tools/.cipd_bin/ninja because depot_tools recipe bundle doesn't setup .cipd_bin.

It needs to ensure .cipd_bin by calling cipd_bin_setup.{sh, bat} before calling ninja in the depot_tool recipe module.
This CL bundles more files required to call cipd_bin_setup.
