when called with broken systemd unit file, the daemon is killed by systemd.

[christf]

this will cause logs being filled like crazy with the following message: retrying, sendmsg on rtmgr_rtnl_talk(): Socket operation on non-socket

There are multiple things contributing to it:

• [ ] l3roamd should not be started with a client interface that does not exist, add routes => fix salt and init scripts
• [x] l3roamd should be able to cope with garbage being thrown at it
• [x] l3roamd should not attempt socket operations on non-sockets (wtf)

there is a horrible workaround for this for now that will only retry for 5 times. The root cause should be found & fixed.

Now only the unit file is left to be fixed.

fixing the unit file is not an l3roamd issue => closing.
