dd4963d3 - - Change to call JNU_GetStringPlatformChars, JNU_ClassString and JNU_NewStringPlatform

- Change to call JNU_GetStringPlatformChars, JNU_ClassString and JNU_NewStringPlatform using the function addresses obtained from lookup. This allows building libstringPlatformChars without explicitly linking with libjava.so (or libjava.dll). - Remove #include "jni_util.h". - Add BUILD_JDK_JTREG_LIBRARIES_LDFLAGS_libstringPlatformChars := -ldl. It's needed to avoid build failure if the build is configured to not allow undefined symbols in shared library.
