8268974: GetJREPath() JLI function fails to locate libjava.so if not standard Java launcher is used

[snazarkin]

I'd like to backport this changes as it fixes some custom launchers issue. The backport is not clean:

1. 8234821 was not backported to jdk11, so java_md_common.c need manual adjusting.
2. The test can't be started as it depends on whole jpackage test pack. So I've removed it.

The functionality was tested with simple

cd ~/tools/bin
cp -r ~/jdk .
cp jdk/bin/java jdk/lib
jdk/lib/java -version

Without the patch it show the error

       Error: could not find libjava.so
       Error: Could not find Java SE Runtime Environment.

jdk_tier2 is OK as well
