bpf: Replace strncpy() with strscpy()
Using strncpy() on NUL-terminated strings is considered deprecated[1].
Moreover, if the length of 'task->comm' is less than the destination buffer
size, strncpy() will NUL-pad the destination buffer, which is a needless
performance penalty.
Replacing strncpy() with strscpy() fixes all these issues.
