Update net-tests-utils-host-common tag to "mts-networking"

We use "mts-networking" and not "mts" so that the tests and test dependencies can be properly included in the automated MTS packaging and release (go/mts-packaging).
Instead of tagging tests "mts", we should use "mts-*" where the suffix is one of https://source.corp.google.com/android/test/mts/tools/build/config.mk;l=19.
