Fix test added by commit 9de9294b.

The buildfarm members "drongo" and "fairywren" reported that
the regression test (024_archive_recovery.pl) added by commit 9de9294b
failed. The cause of this failure is that the test calls $node->init()
without "allows_streaming => 1" and which doesn't add pg_hba.conf
entry for TCP/IP connection from pg_basebackup.
This commit fixes the issue by specifying "allows_streaming => 1"
when calling $node->init().
