Michael Smith a7d7336531 IMPALA-12566: Fix RpcMgrKerberizedTest on RedHat 8 ...

On RedHat 8, RpcMgrKerberizedTest cases fail with

  Jan 09 14:47:03 msmith.vpc.cloudera.com krb5kdc[609624](info): TGS_REQ
  (1 etypes {aes128-cts-hmac-sha1-96(17)}) 127.0.0.1: LOOKING_UP_SERVER:
  authtime 0, etypes {rep=UNSUPPORTED:(0)}
  impala-test/msmith.vpc.cloudera.com@KRBTEST.COM for
  impala-test/msmith@KRBTEST.COM, Server not found in Kerberos database

This happens because bootstrap_system.sh adds an entry to /etc/hosts to
resolve 127.0.0.1 to hostname and puts the short hostname first. During
negotiation, Kudu RPC will call GetFQDN to retrieve the FQDN, which for
our tests running on localhost returns the short hostname.

Fixes RpcMgrKerberizedTest by swapping the order of entries added to
/etc/hosts so the FQDN comes first. This is consistent with the example
provided in https://man7.org/linux/man-pages/man5/hosts.5.html.

Avoids 'hostname -f'; on RedHat it's identical to 'hostname', and on
Ubuntu it causes this test to fail.
