John Baldwin c79c04f176 Use the regular poll(2) function to implement poll(2) for the IBCS2 compat
ABI as FreeBSD's poll(2) is ABI compatible.  The ibcs2_poll() function
attempted to implement poll(2) using a wrapper around select(2).  Besides
being somewhat ugly, it also had at least one bug in that instead of
allocating complete fdset's on the stack via the stackgap it just allocated
pointers to fdsets.
