tdeioslave media: fixed update of mime type on encrypted CD/DVD devices caused by missing

udev events. Note: not sure if the bug was only specific to VirtualBox
"iso" CD/DVD or general for any CD/DVD. In any case this fix is required
if using LUKS encrytped .iso files with TDE running inside VirtualBox.
