Subject: [PATCH 1/2] Fix 'doctor' command failing at Cocoapods stage when user
 uses ASDF.

If the user is using ASDF the 'doctor' command may fail at the Cocoapods stage as it will be using the global tool definitions instead of those specified by the project (if any).  This fixes the problem by generating a .tool-versions file with the correct settings in the temp directory used for the Cocoapods test.
