Fix reversion in use of ikiwiki -verbose -setup with a setup file that enables syslog.

Setup output is once again output to stdout in this case.

Implemented by stashing the verbose/syslog values set in the setup file,
and using those values in the generated wrappers, but not allowing them to take
effect during the setup operation itself, so that command-line options,
appearing before or after -setup, are honored.

Also, some cleanups to how %config is generated for wrappers, removing some
fields that do not need to be recorded inside the wrapper.
