Set include_realm=1 default in parse_hba_line
With include_realm=1 being set down in parse_hba_auth_opt, if multiple
options are passed on the pg_hba line, such as:
host all all 0.0.0.0/0 gss include_realm=0 krb_realm=XYZ.COM
We would mistakenly reset include_realm back to 1. Instead, we need to
set include_realm=1 up in parse_hba_line, prior to parsing any of the
additional options.
