BUG/MINOR: filters: Invert evaluation order of HTTP_XFER_BODY and XFER_DATA analyzers

These 2 analyzers are responsible of the data forwarding in, respectively, HTTP
mode and TCP mode. Now, the analyzer responsible of the HTTP data forwarding is
called before the one responsible of the TCP data forwarding. This will allow
the filtering of tunneled data in HTTP.

[wt: backport desired in 1.7 - no impact right now but may impact the ability
 to backport future fixes]
