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.

-         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>.
