Bug 681: Add Elf Parsing for other OS than Linux, if ARM and !ANDROID using /proc/self/exe (Linux) or a found java/jvm native lib.

- PlatformPropsImpl.queryABITypeImpl: Check Elf Header for ARM + !ANDROID (i.e. add other OS than Linux, use native java/jmv lib)
- NativeLibrary.enumerateLibraryPaths: Add 'sun.boot.library.path' to enumeration!
- TestElfReader01: Add test for finding java/jvm native lib and parse it
