Add NetworkSecurityUnitTests to tethering-mainline-presubmit

Test with connectivity/tethering module only, to catch integration issues with older versions of other modules.

Only the unit test are added to the test_mapping for now. The CTS tests are not compatible with older dessert releases.

The min_sdk_version in the test build target should help preventing the
regressions from b/398885474.
