shill: Only list net/ source files once in BUILD.gn

CL:947318 modifies shill's build such that net/ source files are built
twice--once for shill, and once for a shared DLL using different
compilation flags. It is inconvenient to insist that developers remember
that newly-added net/ source files must be specified twice in the build
file, however. This change instead places the net source files in a
"net_sources" list that is used by both targets.

BUG= chromium:897985 
TEST=`cros_workon_make --board ${BOARD} shill --test` succeeds.
     Adding a non-existent source file to net_sources causes the build
     to fail.
