gdb, gdbserver: update copyright years in copyright notices

The copyright notices printed by these programs still use year 2024.
Update to 2025.

It seems like a trivial patch to me, but I am posting it for review, in
case there's something wrong in the new-year process that caused them to
be missed, in which case we should address that too.
