uml: remove duplicate config symbol and unused file and variables
Fix the repetition of the NET symbol. It was once in UML specific options and once in networking. I removed the first occurrence, as it makes more sense to me to keep it only in networking. It also removes a mostly empty file which is not used anymore and some unused variables.

- bool "Networking support"
- help
- Unless you really know what you are doing, you should say Y here.
- The reason is that some programs need kernel networking support even
- when running on a stand-alone machine that isn't connected to any
- other computer. If you are upgrading from an older kernel, you
- should consider updating your networking tools too because changes
- in the kernel and the tools often go hand in hand. The tools are
- contained in the package net-tools, the location and version number
- of which are given in <file:Documentation/Changes>.
-
- For a general introduction to Linux networking, it is highly
- recommended to read the NET-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
