file(DOWNLOAD): Make TLS options behave as documented 

The logic added in commit e1c89f08 (file(DOWNLOAD): Add options for SSL,
2012-08-21) did not actually provide the documented behavior.  Simplify
the implementation to read the variable values first and then replace
them with the explicit argument values if encountered.  Always set the
curl option CURLOPT_SSL_VERIFYPEER to either on or off explicitly
instead of depending on the curl default behavior.
