remove misguided action parameters

This feature was introduced with

 commit 02a4c5101ca4751963f76a0e016d3308389dc2a5

It makes things a lot harder for privilege granting if a feature like
action parameters are present. Thinking about it, they're not really
necessary; the parameters should just be encoded in the resource name;
e.g. with the example given in the commit

is broken; the right thing here is for a hypothetical NetworkManager
to pass the dial up connection details as the resource

 resource.type = "NetworkManager"
 resource.id = "/org/freedesktop/NM/DialUpConnection/number=555-HOT-CHICKS"

in a well-defined format etc. etc.
