base-files: change permissions on /sys and /proc

The kernel mounts /proc and /sys with the mode 555. Fedora explicitly
sets this value in its filesystem setup package. Debian doesn't seem
to set it explictly.  Having them be 755 causes permission issues on
upgrades inside a container where the guest does not have the
permission to change the modes of the mount points.

So, just bite the bullet and force them to be 555.
