tests/net/socket/ faults on sam_e70_xplained and frdm_k64f

[nniranjhana]

The tests in tests/net/socket/tcp and tests/net/socket/getaddrinfo run into MPU fault after the tests start.

The tests started failing after this commit: 18cec24
which is part of #9179 that adds system calls to socket APIs. What do we do here?
