remove useless infinite loop from end of exit function

this was originally added as a cheap but portable way to quell
warnings about reaching the end of a function that does not return,
but since _Exit is marked _Noreturn, it's not needed. removing it
makes the call to _Exit into a tail call and shaves off a few bytes of
code from minimal static programs.
