random: xoshiro128: reseed state on entropy fail When requesting seed entropy data fails, reseed the PRNG state with runtime data. This is a minimal effort to ensure that random data requested before a backing entropy device is ready does not result in repeatable data on each boot. The random XOR integers are selected from the CRC32 algorithm. Signed-off-by: Jordan Yates <jordan.yates@data61.csiro.au>
