Azeem Shaikh acf15e07eb netfilter: ipset: Replace strlcpy with strscpy 
strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().

Direct replacement is safe here since return value from all
callers of STRLCPY macro were ignored.
