[PATCH] of/flattree: Replace all non-returning strlcpy with strscpy

[Azeem Shaikh <azeemshaikh38@gmail.com>]

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().
No return values were used, so direct replacement is safe.
