configure: change default for sysconfdir to /etc

Otherwise some important stuff (initscript, files for logrotate, cron, udev)
will be installed to some nonsense place like /usr/local/etc/ etc.).

We do not want to ask user to supply --sysconfdir=/etc on every ./configure
invocation thus this (somewhat controversial) patch. If you have better idea,
please tell us :)
