Bug #13164 yassl: "SSL connection error" on several platforms

 - it's a requirement fo yaSSL that either /dev/urandom or /dev/random is available on the target system.
 - Added a fix that tries to open /dev/random if /dev/urandom is not available.

  Try to open /dev/ranom if /dev/urandom is not available.
