RFR (trivial): 8235833: PosixPlatform.cpp should not include sysctl.h

[Yasumasa Suenaga]

Hi Andrew,

I can see same error whether --disable-precompiled-headers or not.
So I filed it to JBS and uploaded webrev.
Could you review it?

   JBS: https://bugs.openjdk.java.net/browse/JDK-8235833
   webrev: http://cr.openjdk.java.net/~ysuenaga/JDK-8235833/webrev.00/

It works fine on Fedora 31.
I've pushed it to submit repo. I believe it passes all tests.


Thanks,

Yasumasa
