fix: correct output flag name in inspect_fcntl_or_open_flags

The function was incorrectly outputting 'O_SYNC' when checking for
the O_NDELAY flag. This was likely a copy-paste error that could
cause confusion when debugging file descriptor flags.

The issue was in the inspect_fcntl_or_open_flags function where
the condition checked for O_NDELAY but output the wrong flag name.

Changed:
- Fixed output from 'O_SYNC' to 'O_NDELAY' to match the actual flag being checked
