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.
