exit: add internal include file with helpers
Move struct wait_opts and waitid_info into kernel/exit.h, and include
function declarations for the recently added helpers. Make them
non-static as well.
This is in preparation for adding a waitid operation through io_uring.
With the abtracted helpers, this is now possible.
