modules: make sysfs attribute files readable by owner only
This code goes back to the historical bitkeeper tree commit 3f7b0672086
("Module section offsets in /sys/module"), where Jonathan Corbet wanted
to show people how to debug loadable modules.
See
https://lwn.net/Articles/88052/
from June 2004.
To expose the required load address information, Jonathan added the
sections subdirectory for every module in /sys/modules, and made them
S_IRUGO - readable by everybody.
It was a more innocent time, plus those S_IRxxx macro names are a lot
more confusing than the octal numbers are, so maybe it wasn't even
intentional. But here we are, thirteen years later, and I'll just change
it to S_IRUSR instead.
Let's see if anybody even notices.
