[PATCH v3 0/6] Update clone3 self-tests

[Eugene Syromiatnikov <esyr@redhat.com>]

Hello.

This patch set updates clone3 selftest in several aspects:
 - adding checks for exit_signal invalid values handling;
 - adding clone3 to selftests targets;
 - enabling clone3 tests on all architectures;
 - minor cleanups of the clone3 test.

This respin alignes additional clone3 self-tests with v3 of the
exit_signal checking patch[1].

Applied on top of brauer/linux.git/for-next.

Changes since v2[2]:
 - CLONE3_ARGS_INVAL_EXIT_SIGNAL_NSIG check is now expected to fail.

Changes since v1[3]:
 - exit_signal check extended to cover more cases of invalid
   exit_signal value.
