The message logged and the exception raised by nlmanager, when receiving
an NLMSG_ERROR packet from the kernel, wasn't super explicit plus if the
error wasn't a netlink related failure we didn't provide any information
Now we use strerror with the provided error code to generate a nice msg.

We used to have these checks in the old rtnetlink python library.
They were missing in python-nlmanager this was a big regression for
ifupdown2.

For now, we use a mirror copy of nlmanager sources to make sure we don't
depend on it as an external package
