If the satellite registration url was specified with https, the curl
command to detect the satellite version would not work as expected since
-L was not passed and you get redirected to https when testing the ping
api.
To additionally handle the case where https is specified, also use curl
directly with -k to download the configuration rpm instead of using rpm
with a url.
Fixes another bug with a missing $ in the reference to the
$satellite_version variable.
