[Bug translator/10641] New: -m NAME should be disabled in --unprivileged mode

We need to restrict the '-m NAME' option. It allows users to insert modules that
then block the loading of "real" modules. Example "attack":
% stap --unprivileged -m nfs -e 'probe begin { log("registered as nfs!"); }"'
registered as nfs!
% mount -t nfs nescio:/home /home/nescio
mount.nfs: No such device
[kill stap]
% mount -t nfs nescio:/home /home/nescio
[and now it is mounted]
