Clean up connman-conf on systemd systems

As reported in YP#8399 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.

Since v4 I've rebased on master and updated the unit file to have the path to the script sed'ed in, as the script location has changed since the original submission.

Tested by 1) booting a qemux86 and validating the network was brought up per the wired.config settings 2) booting a genericx86 image and checking that the wired-connection.service isn't installed.

Regards,

Joshua

From: Joshua Lock <[email protected]>

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

From: Joshua Lock <[email protected]>

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

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.
