RFR: 8268974: GetJREPath() JLI function fails to locate libjava.so if not standard Java launcher is used [v4]

[Alexey Semenyuk]

> GetApplicationHomeFromDll() fails if the path to libjli.so contains "bin" component (/tmp/bin/HelloWorld/lib/runtime/lib/libjli.so). TruncatePath() looks for "/bin/" first in "/tmp/bin/HelloWorld/lib/runtime/lib/libjli.so" string and then it looks for "/lib/". But this is wrong order as it should look for "/lib/" first. I.e. TruncatePath() should look for "/bin/" and then for "/lib/" if called from GetApplicationHome() and for "/lib/" first and then for "/bin/" if called from GetApplicationHomeFromDll().
