e953aeaa91 selftests/clone3: Avoid OS-defined clone_args
As the UAPI headers start to appear in distros, we need to avoid
outdated versions of struct clone_args to be able to test modern
features, named "struct __clone_args". Additionally update the struct
size macro names to match UAPI names.

51ad5b54b6 selftests/clone3: Reorder reporting output
Selftest output reporting was happening before the TAP headers and plan
had been emitted. Move the first test reports later.

selftests/clone3: skip if clone3() is ENOSYS
If the clone3() syscall is not implemented we should skip the tests.

41585bbeee selftests: add tests for clone3() with *set_tid
This tests clone3() with *set_tid to see if all desired PIDs are working
as expected. The tests are trying multiple invalid input parameters as
well as creating processes while specifying a certain PID in multiple
PID namespaces at the same time.

Additionally this moves common clone3() test code into clone3_selftests.h.

Test that CLONE_CLEAR_SIGHAND resets signal handlers to SIG_DFL for the
child process and that CLONE_CLEAR_SIGHAND and CLONE_SIGHAND are
mutually exclusive.
