ureport: use entit certs with 'rhsm' and drop 'rhsm-entitlement'

/etc/pki/consumer certificates cannot be used for authentication in
Strata. Martin Milata has correctly pointed out that it does not make
sense to have both 'rhsm' and 'rhsm-entitlement' options.

rhtsupport: never use uReport URL from ureport.config

The GUI reporter always export uReport_URL, thus reporter-rhtsupport
never use the Strata URL.

Moreover, usage of uReport_URL is really bad idea, because a reporter
thinks he is going to send data to the portal but the ureport might end
somewhere else.
