RNG not initialised for sftp only under Solaris.

[mouring at etoh.eviladmin.org]

Ahh.. a moment of truth.  the init_rng(); does being in sftp.c due to:

sftp-client.c:  id = arc4random();              
sftp-client.c:  id = arc4random();              
sftp-client.c:  id = arc4random();              
sftp-client.c:  id = arc4random();              
sftp-client.c:  id = arc4random();              
sftp-client.c:  id = arc4random();              
sftp-client.c:  id = arc4random();              
sftp-client.c:  id = arc4random();              
sftp-client.c:  id = arc4random();              
sftp-client.c:  id = arc4random();              
sftp-client.c:  expected_id = id = arc4random();
sftp-client.c:  id = arc4random();              
sftp-client.c:  id = arc4random();              
sftp-client.c:  id = arc4random();              

Ok.. This makes much more sense.=)
