This reverts commit d3bfd23c.

Reason for revert: Breaks non-depot_tools based presubmits that use canned checks that expect the presubmit to be run in the sub-repository (for example, in Catapult where it's hosted in third_party/catapult instead of being directly in chromium).

Original change's description:
> presubmit_canned_checks: Run pylint on parent directory for depot_tools.
> 
> On Windows, scripts on the current directory take precedence over PATH.
> When pylint.bat calls vpython, it executes the vpython of the depot_tools
> under test instead of the one in the bot.
> As a workaround, run the tests from the parent directory instead.
