PR61009: be as helpful as possible during -V operation

A configtest isn't useful if you're just trying to get compile settings.
Move the settings dump up to just after ap_read_config(), which has
already done the minimum necessary to figure out which MPM is in use.

Even if ap_read_config() failed, still print as many compile settings as
we can. The user will see the error log entry on stderr.
