Do not apply "rsync by module" hack to TA rsyncs

Do not apply "rsync by module" hack to TA rsyncs

Let:

- A = The TA and RPP share rsync modules
- B = RRDP is available

If the "rsync by module" hack is applied to TAs and Fort downloads the
TA by rsync,

- If A and B, Fort performs 1 big rsync and 1 big RRDP update
- If A and !B, Fort performs 1 big rsync
- If !A and B, Fort performs 1 single-file rsync and 1 big RRDP update
- If !A and !B, Fort performs 1 single-file rsync and 1 big rsync

If the "rsync by module" hack is not applied to TAs and Fort downloads
the TA by rsync,

- If A and B, Fort performs 1 single-file rsync and 1 big RRDP update
- If A and !B, Fort performs 1 single-file rsync and 1 big rsync
- If !A and B, Fort performs 1 single-file rsync and 1 big RRDP update
- If !A and !B, Fort performs 1 single-file rsync and 1 big rsync

So not applying the hack on TAs is more cache-efficient.
