[MINOR] buffer: refine the flags that may wake an analyser up.

Analysers don't care (and must not care) about a few flags such as
BF_AUTO_CLOSE or BF_AUTO_CONNECT, so those flags should not be listed
in the BF_MASK_STATIC bitmask.

We should also recheck if some buffer flags should be ignored or not
in process_session() when deciding if we must loop again or not.
