BUG/MAJOR: lua: Do not force the HTTP analysers in use-services

INNER and XFERBODY analyzer were set in order to support HTTP applets
from TCP rulesets, but this does not work (cf previous patch).

Other cases already provides theses analyzers, so their addition is
not needed. Furthermore if INNER was set it could cause some headers
to be rewritten (ex: connection) after headers were already forwarded,
resulting in a crash in buffer_insert_line2().

Special thanks to Bernd Helm for providing very detailed information,
captures and stack traces making it possible to spot the root cause
here.

This fix must be backported to 1.6.
