samples: drivers: crc: fix twister regex and run in CI

1. Update the CRC sample’s Twister console regex to match the current
log output.
2. Add an integration_platforms entry (ek_ra8m1) so the sample runs
in PR CI.
3. Make CRC verification unconditional so the expected
“verification succeeded” log is always emitted and mismatches fail
the test.
