[PATCH v2] media: verisilicon: Replace strlcat() with scnprintf()

[Mariia Nikitash <nikitash.mariiaw@gmail.com>]

In preparation for removing the deprecated strlcat() API [1], replace the
strscpy() and strlcat() calls in hantro_add_func() with a single
scnprintf() call.

This preserves the resulting string, including NUL termination
and truncation behavior.

Changes in v2:
- Replace seq_buf with a single scnprintf() call, as suggested
  by Hans Verkuil.
