dnsdist: Fix eBPF filtering of long qnames

This commit switches to the use of eBPF positive offsets to access
the content of the transport and application layers, since using
negative offsets (needed to access the other layers) led to issues
with long qnames.
This is cleaner anyway :-)

(cherry picked from commit abbc72876eabc7a1745f50e7a9ff4c41b4bbef62)
