Subject: [PATCH] copy_class_filename: replace deprecated strlcpy with strscpy

The latest kernel docs:
https://www.kernel.org/doc/html/latest/process/deprecated.html
recommends replacing strlcpy with strscpy as the safer alternative. The
value of strlcpy is not used so there shouldn't be issues with replacing
the deprecated call.
