gdb: pass child_ptid and fork kind to target_ops::follow_fork

Browse source 
This is a small cleanup I think would be nice, that I spotted while
doing the following patch.

gdb/ChangeLog:

	* target.h (struct target_ops) <follow_fork>: Add ptid and
	target_waitkind parameters.
	(target_follow_fork): Likewise.
	* target.c (default_follow_fork): Likewise.
	(target_follow_fork): Likewise.
	* fbsd-nat.h (class fbsd_nat_target) <follow_fork>: Likewise.
	* fbsd-nat.c (fbsd_nat_target::follow_fork): Likewise.
	* linux-nat.h (class linux_nat_target) <follow_fork>: Likewise.
	* linux-nat.c (linux_nat_target::follow_fork): Likewise.
	* obsd-nat.h (class obsd_nat_target) <follow_fork>: Likewise.
	* obsd-nat.c (obsd_nat_target::follow_fork): Likewise.
	* remote.c (class remote_target) <follow_fork>: Likewise.
	* target-debug.h (target_debug_print_target_waitkind): New.
	* target-delegates.c: Re-generate.
