[pca] Issue with wget on RHEL6.5

Happy new year to everbody!

Yeah, you had reported this problem already back in May 2013, and I had 
added the temporary fix for the CSW version of wget back then. The root 
cause was (and is) a problem with Oracle's web server:

   https://www.opencsw.org/mantis/view.php?id=5068

Oracle's web admin team planned to upgrade the web server to support 
clients with recent versions of OpenSSL, but it seems as if this never 
happened. They put a note into Support Document 1199543.1, which is 
still there:

   IMPORTANT:

   https://getupdates.oracle.com web server does not fully support TLS
   1.2. Only OpenSSL versions from branch 1.0.0 will work - Oracle
   Solaris does not deliver higher versions at this time.
   Customers who are trying to access the URL using latest wget/OpenSSL
   (ie. from www.opencsw.org) version with TLS 1.2 support may get
   connection failures.

Did exactly that in the current development release of PCA now. It seems 
as if the --secure-protocol option is supported in all relevant versions 
of wget, so this should do no harm.

Thanks for the report!

Martin.
