Azeem Shaikh 2933d3cd07 tracing: Replace strlcpy with strscpy in trace/events/task.h ...

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.
