The PCI sysfs rom file is exposed read-only by default, but we need

running as root, the code works fine as is, but when running
de-privileged via libvirt, the fopen("r+") will fail if the file
doesn't have owner write permissions. libvirt already gives us
ownership of the file, so we can toggle this around the short
usage window ourselves.
Why is qemu in the business of chmod()ing resources? If qemu needs
write access to some resource, the user needs to provide that access.
