RFR 8241888: Mirror jdk.security.allowNonCaAnchor system property with a security one

[Martin Balao]

Hi,

I'd like to request a review for 8241888 [1].

Webrev.00:

 * http://cr.openjdk.java.net/~mbalao/webrevs/8241888/8241888.webrev.00/

CSR (waiting for review): https://bugs.openjdk.java.net/browse/JDK-8241893

I've not included my regression test as it's a trivial change and my
test is actually testing SecurityProperties -which has already been tested-.

Thanks,
Martin.-
