Kernel/ProcFS: Remove all unnecessary components

Now that all global nodes are located in the /sys/kernel directory, we
can safely drop the global nodes in /proc, which includes both /proc/net
and /proc/sys directories as well.
This in fact leaves the ProcFS to only have subdirectories for processes
and the "self" symbolic link to reflect the current process being run.
