IMPALA-5041: Calling AuthManager::Init() more than once results in undefined behavior

We use a global variable to track the completion of the
kerberos environment setup which shouldn't be the case since
we would want to re-setup the environment if we call
AuthManager::Init() with a different configuration. Currently, if
we call it again, some of our new configuration get applied,
whereas some don't.

Also, the global variable 'env_setup_complete_' was used so that
we don't set the environment twice (once for internal transport and
once for external). This patch ensures that it's still the case.
