Simon Levermann ad5be08a07 Ignore some non-interesting filesystem types
Generally, how much space we have in squashfs, or tmpfs shouldn't
interest us. This becomes more relevant in distros like Ubuntu, where
snaps are a thing, and each snap mounts their own FS in a squashfs that
is always full, thus falsifying the output of sysinfo.
