java/openjdk25: Update to OpenJDK 25.0.2

Update to track upstream version 25.0.2, with fixes for FreeBSD.

See the upstream release notes for details on what has changed since
version 25.0.1:
https://www.oracle.com/java/technologies/javase/25-0-2-relnotes.html

In addition to the above, this release includes the following patch,
scheduled for JDK 26 by upstream.

JDK-8371637: allocateNativeInternal sometimes return incorrectly aligned
memory

This is because this patch affects systems using jemalloc specifically,
like FreeBSD does, but I feel it's too long time to wait until the next
LTS release before making it available on FreeBSD.
