Revert of Turn on hermetic toolchain for all corp machines. (patchset #2 id:20001 of https://codereview.chromium.org/2445993004/ )

Reason for revert:
This break developer workflow for Googlers (as build/mac/should_use_hermetic_xcode.py returns 1) as the hermetic build does not contains support for iOS SDK, thus "gn gen" fails with the following error:

$ gn gen --args='target_os="ios"' out/default
ERROR at //build/config/ios/ios_sdk.gni:98:21: Script returned non-zero exit code.
  _ios_sdk_result = exec_script(script_name, ios_sdk_info_args, "scope")

The was not caught by the bots because they do not set FORCE_MAC_TOOLCHAIN and are not corporate machine.
