kdb: address -Wformat-security warnings

[ Upstream commit 70867efacf4370b6c7cdfc7a5b11300e9ef7de64 ]

When -Wformat-security is not disabled, using a string pointer
as a format causes a warning:

kernel/debug/kdb/kdb_io.c: In function 'kdb_read':
kernel/debug/kdb/kdb_io.c:365:36: error: format not a string literal and no format arguments [-Werror=format-security]
  365 |                         kdb_printf(kdb_prompt_str);
      |                                    ^~~~~~~~~~~~~~
kernel/debug/kdb/kdb_io.c: In function 'kdb_getstr':
kernel/debug/kdb/kdb_io.c:456:20: error: format not a string literal and no format arguments [-Werror=format-security]
  456 |         kdb_printf(kdb_prompt_str);
      |                    ^~~~~~~~~~~~~~

Use an explcit "%s" format instead.
