kdb: Remove optional size arguments from strscpy() calls

Browse Source 
If the destination buffer has a fixed length, strscpy() automatically
determines the size of the destination buffer using sizeof() if the
argument is omitted. This makes the explicit sizeof() unnecessary.

Furthermore, CMD_BUFLEN is equal to sizeof(kdb_prompt_str) and can also
be removed. Remove them to shorten and simplify the code.

No functional changes intended.
