Add negative integration tests for sync syscalls (task 348)

Add three EBADF scenarios testing ior's ability to capture sync-related
tracepoints even when the underlying syscall fails:

- sync-fsync-ebadf: fsync on invalid fd, expects enter_fsync
- sync-fdatasync-ebadf: fdatasync on invalid fd, expects enter_fdatasync
- sync-file-range-ebadf: sync_file_range on invalid fd, expects enter_sync_file_range
