[PATCH linux-next] perf intel-pt: replace strlcpy() with strscpy()

[<yang.guang5@zte.com.cn>]

From: Yang Guang <yang.guang5@zte.com.cn>

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