[PATCH 3/4] kdb: Replace deprecated strcpy() with memcpy() in parse_grep()

[Thorsten Blum <thorsten.blum@linux.dev>]

strcpy() is deprecated; use memcpy() instead.

We can safely use memcpy() because we already know the length of the
source string 'cp' and that it is guaranteed to be NUL-terminated within
the first KDB_GREP_STRLEN bytes.
