RFR: [9]: 8151834: Test SmallPrimeExponentP.java times out intermittently

[Rajan Halade]

Hi Max,

Please review this patch to fix SmallPrimeExponentP test. It now uses 
fixed seed value to generate keypair. I did several rounds of testing on 
different machines to make sure that primes 63/65 are generated in fixed 
number of iterations. Other updates to test are done to include detailed 
summary and to log debug information.

Thank you for your help with the fix to have constant seed.

Thanks,
Rajan
