There were two issues with the carp key configuration in the new netlink
code.
The first is that userspace failed to actually pass the CARP_NL_KEY
attribute to the kernel, so a key was never set.
The second issue is that snl_attr_get_string() returns a pointer to the
string inside the netlink message. It does not copy the string to the
target buffer. That's somewhat inconvenient to work with in libifconfig
where we have a static buffer for the key.
Introduce snl_attr_copy_string() which can copy a string to a target
buffer and uses the 'arg' parameter to pass the buffer size, so it
doesn't accidentally exceed the available space.
