mod_cgid:

fix parmlist to ap_open() so that we can open the ScriptLog file o.k.

in log_script(), don't do anything with script_err parm if it is NULL
(for mod_cgid, it is always NULL; rather than simply ripping out such
logic I kept it in case somebody wants to factor out common parts of
mod_cgi.c and mod_cgid.c later)
