[PATCH] sunjre: check all four possible OpenJDK variants for libjvm.so

Since OpenJDK 21, the "minimal" and "zero" variants of JVM no longer
reside in the "server" directory in $JAVA_HOME/lib, making the loader
unable to find libjvm.so. This regresses LO builds on platforms with
only those variants of JVM (i.e. without a HotSpot port).

Example error message is like this:

> exception occurred: Could not create Java implementation loader at
> ./stoc/source/javaloader/javaloader.cxx:551

Fix it by probing all four possible variant directories for libjvm.so.
This is tested on Debian unstable (loong64 port) to fix the packaging.
