IMPALA-6281: Fix use-after-free in InitAuth()

Previously, we implicitly create a local string object created from
the char* in argv[0] when calling InitAuth(). This string object goes
out of scope once InitAuth() returns but the pointer of this local
string's buffer is passed to the Sasl library which may reference
it after the local string has been deleted, leading to use-after-free.

This change fixes the problem above by passing the char* argv[0]
directly into InitAuth() and eventually to the Sasl library which
takes a const char* as argument anyway.

Testing done: Verified rpc-mgr-test and thrift-server-test no longer
fail in ASAN build.
