gdb: remove add_alias_cmd overload that accepts a string

Same idea as previous patch, but for add_alias_cmd.  Remove the overload
that accepts the target command as a string (the target command name),
leaving only the one that takes the cmd_list_element.

gdb/ChangeLog:

	* command.h (add_alias_cmd): Accept target as
	cmd_list_element.  Update callers.
