connman: Wired inteface provisioned via qemu

- connman-conf package re-implemented
- connman 1.12 introduces provisioning for
wired interfaces also;
- wired interface settings are read from
kernel cmdline if present;
- after that are passed to connman as a
config file
- for BA, this is not needed, as BA will
have a network infrastructure to work with.

Fixes [YOCTO #3227];
Fixes [YOCTO #3804];
Fixes [YOCTO #3843].
