RFR: 8209837: Avoid initializing ExpiringCache during bootstrap

[Remi Forax]

Hi Claes,

  useCanonPrefixCache = useCanonCaches ? getBooleanProperty("sun.io.useCanonPrefixCache",false) : false;
can be written
  useCanonPrefixCache = useCanonCaches && getBooleanProperty("sun.io.useCanonPrefixCache",false);

and the name useCanonCaches/useCanonPrefixCache should follow the coding convention USE_CANON_CACHES/USE_CANON_PREFIX_CACHE.

otherwise, looks good !
