selftests: drv-net: enable devmem TCP in the test config

The config fragment already sets CONFIG_UDMABUF=y, but kconfig silently
drops it. UDMABUF/NET_DEVMEM both depend on DMA_SHARED_BUFFER, which we
can't enable directly, so we need to enable a config that selects it. We
use SYNC_FILE for that purpose here.

Additionally, we flip on CONFIG_NET_DEVMEM as well.
