Comment 11 for bug 1757143

After chatting with xnox on IRC, he discovered that the output of catting /proc/modules in 4.15 now depends on who is doing the catting.

So `cat /proc/modules` as a normal user will return null references while `sudo cat /proc/modules` will return the actual memory offsets, accurately.

For example:
ubuntu@xwing:~$ sudo cat /proc/modules |grep e1000e
e1000e 249856 0 - Live 0xffffffffc0225000
ptp 20480 2 igb,e1000e, Live 0xffffffffc00a9000
ubuntu@xwing:~$ cat /proc/modules |grep e1000e
e1000e 249856 0 - Live 0x (null)
ptp 20480 2 igb,e1000e, Live 0x (null)

So for the cert tooling, this should be a simple fix then, just to ensure that the module script runs as root.
