detect file: improve multi file handling

When multiple files were in a tx, the first one(s) closed/complete
and a new open one as well, a match in the former could lead to not
inspecting the latter.

This patch adds a workaround for this case, by allowing the file
inspection code to return a special code for 'match, but more files
available in tx'.

The stateful detection engine will then not make this match final for
the tx. It relies on the file pruning to kick in to make sure the
already complete files are removed from the tx before the next time
the detection engine is called on the tx.
