- unix: add Darwin support for clonefile syscalls
- Adds openat2 for linux
  openat2 is a new syscall added to Linux 5.6. It provides a superset of
  openat(2) functionality, extending it with flags telling the kernel how
  to resolve the paths.

  For more info, see https://lwn.net/Articles/803237/

  NOTE that this is a second attempt to add the call; the previous one
  (https://golang.org/cl/227280) was reverted
  (https://golang.org/cl/227846) due to the test case failure on ARM
  (https://golang.org/issue/38357).

  This CL has the test case reworked to be less assumptive to the testing
  environment. In particular, it first tries if the most simplistic
  openat2() call succeeds, and skips the test otherwise. It is done that
  way because CI can be under under different kernels and in various
  envrionments -- in particular, Docker+seccomp can result in EPERM from a
  system call (which is not expected otherwise).

  For previous discussions about the test case, see
  https://golang.org/cl/227865.
