pgsql: Set include_realm=1 default in parse_hba_line

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.

Discovered by Jeff McCormick during testing.

Bug introduced by 9a08841.
