fix for replace build dir inside webdriverio dir

[shantanuk-browserstack]

To get the correct location of package.json inside the webdriverio directory, we were replacing the webdriverio/build directory in path to webdriver/package.json.

When using this in buildkite pipeline, this was causing the error Error: Cannot find module as buildkite by default creates the build directory, the code was replacing this directory.
