[SMF] Separate EPC-only attach config to avoid NRF register timeout

Previously, sample.yaml was used for both 5GC and EPC attach tests.
Because SMF had SBI configured, it sent a register PUT to NRF even in
EPC-only tests (where nrf/scp was not run), leading to a missing HTTP
response and connection timer expiry.

Now, attach.yaml is used for EPC, preventing the unwanted NRF registration.
