fix(systemd-sysext): handle confexts and correct extensions search path

- Support to confexts added in https://github.com/systemd/systemd/pull/26013
(instead of working on /usr and /opt, confext will extend only /etc).

- /usr/lib/extensions/ not supported since https://github.com/systemd/systemd/commit/de862276

- In addition to these two fixes, add only raw binary disk images contained in
regular files, because dracut does not have a helper function to add directories
recursively.
