java/security/SecureRandom/Serialize.java getting time out in linux platform.

Analysis:
The test waits for Entrophy to seed itself but there is Not entropy on /dev/random on Linux.

Fix Required:
1. Call setSeed() before the 1st reseed() or nextBytes() and it will not hang.
Or,
2. Set the system property java.security.egd to /dev/urandom will get entropy from this device and it will not hang.
