Several cleanups related to pipe(2).

- Use `fildes[2]' instead of `*fildes' to make more clear that pipe(2)
  fills an array with two descriptors.

- Remove EFAULT from the manual page. Because of the current calling
  convention, pipe(2) raises a segmentation fault when an invalid
  address is passed.

- Introduce kern_pipe() to make it easier for binary emulations to
  implement pipe(2).

- Make Linux binary emulation use kern_pipe(), which means we don't have
  to recover td_retval after calling the FreeBSD system call.
