Subject: [PATCHv3] Documentation: kgdb: Replace deprecated remotebaud

Using set remotebaud to set the baud rate was deprecated in
gdb-7.7 and completely removed from the command parser in gdb-7.8
(released in 2014). Adopt set serial baud instead.

Change since v2:
  - Add historical example in the documentation
