RFR: 8347506: Compatible OCSP readtimeout property with OCSP timeout [v2]

[Jamil Nimeh]

> This makes a small change to the default value of the `com.sun.security.ocsp.readtimeout` System property.  When not explicitly specified, it will be set to the value of the `com.sun.security.ocsp.timeout` System property, which helps ease the transition from older JDK versions where this property did not exist.
> 
> This change is already part of the [17u backport](https://github.com/openjdk/jdk17u-dev/pull/2747), we are just forward-porting the same change into newer versions.
