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

This is a regression test case for an issue when pids have not been
released on error paths.

selftests/clone3: report a correct number of fails
In clone3_set_tid, a few test cases are running in a child process.  And
right now, if one of these test cases fails, the whole test will exit
with the success status.

selftests/clone3: flush stdout and stderr before clone3() and _exit()
Buffers have to be flushed before clone3() to avoid double messages in
the log.

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.

selftests: add tests for clone3()
This adds tests for clone3() with different values and sizes
of struct clone_args.

This selftest was initially part of of the clone3() with PID selftest.
After that patch was almost merged Eugene sent out a couple of patches
to fix problems with these test.

This commit now only contains the clone3() selftest after the LPC
decision to rework clone3() with PID to allow setting the PID in
multiple PID namespaces including all of Eugene's patches.

tests: test CLONE_CLEAR_SIGHAND
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.
