Fix sim_dv target i2c_host_tx_rx_test

We cherry-picked the i2c dif driver after the IRQ library migration, so
the i2c_host dv test target is actually not buildable. Point it back to
the correct path and we need to fix that again at the next rebase.

This will fix the OT airgap tarball build script
