selftests/eventfd: correct test name and improve messages

- Rename test from eventfd_chek_flag_cloexec_and_nonblock to
eventfd_check_flag_cloexec_and_nonblock.

- Make the RDWR‐flag comment declarative:
  “The kernel automatically adds the O_RDWR flag.”
- Update semaphore‐flag failure message to:
  “eventfd semaphore flag check failed: …”
