credentialprovider: Sets homeDirPath to os.UserHomeDir()

Currently, the credential provider will look in the path set in the $HOME env variable, but that environment does not exist on Windows, but $HOMEPATH does. Because of this, if credentials are set in ~/.docker on Windows, they will not be used by kubelet when pulling images. The function os.UserHomeDir can solve this problem [1].
