[11u] RFR (S) 8220570: Additional trace when native thread creation fails

[Schmelter, Ralf]

Please review this backport to OpenJDK 11u:

Bug: https://bugs.openjdk.java.net/browse/JDK-8220570
orig-change: http://hg.openjdk.java.net/jdk/jdk/rev/a33c42262338 
11u-webrev: http://cr.openjdk.java.net/~rschmelter/webrevs/8220570/webrev.u11.0/

While the patch applied cleanly, an include was missing in the Linux variant for JDK 11 which was not needed for JDK 13.

Best regards,
Ralf
