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.

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>.
