The run.sh script explicitly checks that CONFIG_MODULES is disabled.

By default, this config option is enabled. Explicitly disable it to be
able to run the RDS tests.

Note that writing '# CONFIG_(...) is not set' is usually recommended to
disable an option in the .config, but it looks like selftests usually
set 'CONFIG_(...)=n', which looks clearer.

The ksft CI runtime needs an rds specific config file to build a
minimal kernel with the right options enabled.  This patch adds
an rds selftest config containing the required CONFIG_RDS* and
CONFIG_NET_* options.
