CryptoPkg: RuntimeCryptLib: support realloc(NULL, size)

The ISO C standard says about realloc(),

  If ptr is a null pointer, the realloc function behaves like the malloc
  function for the specified size.

The realloc() implementation doesn't conform to this currently, so add a
check and call malloc() if appropriate.
