configure.ac: improvement
Handle automatically new setttings
--disable-systemd-journal
--disable-appmachineid
Both setting will check presence of apropriate header files.
In case they are present, build will try to automatically build with
them (adding systemd dependency)
User can anytime disabled them and drop systemd dependency.
Also add --with-default-use-devices-file configure option to
select automatically default value for this option.
For this moment keep default upstream as 0
