kdb: kdb_support: replace strcpy() by strscpy()
The strcpy() function is being deprecated. Replace it by the safer
strscpy() and fix the following Coverity warning:
"You might overrun the 129-character fixed-size string ks_namebuf
by copying name without checking the length."
Addresses-Coverity-ID: 138995 ("Copy into fixed size buffer")
