Small cleanup on s3api

This patch is one of follow up to remove unnecessary
files, and a comment in the code.

The conf files are used to setup functests environment
in the past swift3 repository but that should port to
setuppers of functests (see related change). Anyway,
we don't need shell based older conf.in script on that way.
