Bug #5076: keyword content does not work over reassembled TCP

keyword content does not work over reassembled TCP (6.0.x backport)

Description

Using rule
alert ip any any -> any any (content:"HTTP/2.loc"; sid:11;)

on attached pcap

with stream.reassembly.toserver-chunk-size=25

does not trigger an alert

It does trigger the alert without the setting.

I fear we might have an evasion if I split the packets over the default value of 2560...

I do not think we will fix that in 7 soon...
So closing the backport to 6 until there is a fix in master
