Clean up connman-conf on systemd systems

As reported in YP#8399[1] we currently hack the connman service to try and
execute a script which is only installed on qemu targets, its absence on
non-qemu machines results in an error in the journal:
connman.service: Failed at step EXEC spawning /usr/lib/connman/wired-setup: No such file or directory

This pair of patches changes the connman-conf recipe to install a oneshot systemd unit that is called before ConnMan and removes the ExecStartPre.

SysV init based images are unaffected by this change, the existing mechanisms to check for the presence of the wired-setup script from the init script remain in place.

Regards,

Joshua

Install a oneshot unit file that is started before ConnMan to configure a wired network inteface with the wired-setup script, rather than requiring this script to be manually run some how.

2.5.0

connman-conf is now a systemd oneshot and therefore doesn't need to be sed'ed in to the ConnMan service file.

Furthermore we add connman-conf as RRECCOMENDS only for qemu machines.

This cleans up connman-conf so that it is not automatically installed and unconditionally calling a script that doesn't exist for most machines.

Note: this doesn't affect sysvinit where we provide a ConnMan init script which checks for the presence of the wired-networking script and, if it exists, executes it as part of the connman init.
