connman: replace hardcoded path in init script and systemd service
The connman init script sources a setup file from /usr/lib/connman,
so we end up with no network in qemu multilib enabled images.
The init script it's installed by connman and because wired-setup
it's installed by another package (connman-conf) we can't use
libexecdir here and now (in the init script and systemd service file).
Once libexecdir changes from ${libdir}/${bpn} to something else like
/usr/libexec we could use that instead of ${libdir}/connman.
Changed in v2: - better commit message
