[jdk17u-dev] RFR: 8292297: Fix up loading of override java.security properties file

Thu Dec 29 10:10:36 UTC 2022

I backport this for parity with 17.0.7-oracle.

I had to resolve as
8280010: Remove double buffering of InputStream for Properties.load  is not in 17.
The new code comes without the double buffering, but as I understand it is 
also not needed in 17 and thus I left it as-is.
