postfixadmin-cli: drop (undocumented) -webroot etc.

Dropping the -webroot parameter (which basically means hardcoding that
../common.php has to exist) allows to do quite some cleanup.

Also unconditionally require_once('../common.php') to ensure that
everything we expect in the global namespace (like the 'Conf' class) is
there.

This allows even more cleanup. We get rid of __bootstrap() and some
constants, and can simplify parameter handling.
