ftrace: Copy ftrace_graph_filter boot param using strlcpy

We are using strncpy in the wrong way to copy the ftrace_graph_filter
boot param because we pass the buffer size instead of the max string
size it can contain (buffer size - 1). The end result might not be
NULL terminated as we are abusing the max string size.

Lets use strlcpy() instead.
