Let testB141603906 run over ADB-over-network

This test (added in R) failed to take the adb-over-network
case into account like most other tests in the same file. As
such it erroneously fails when tested over such a test setup.
This patch exempts the shell from being subject to the VPN,
like other similar tests do, to avoid the adb connections
being killed.
