batman-adv: Replace usage of strlcpy with strscpy
The strscpy was introduced to fix some API problems around strlcpy. And checkpatch started to report recently that strlcpy is deprecated and strscpy is preferred. The functionality introduced in commit 30035e45753b ("string: provide strscpy()") improves following points compared to strlcpy: * it doesn't read from memory beyond (src + size) * provides an easy way to check for destination buffer overflow * robust against asynchronous source buffer changes Since batman-adv doesn't depend on any of the previously mentioned behavior changes, the usage of strlcpy can simply be replaced by strscpy to silence checkpatch.
