[LTP] syscalls: skip ntfs3 in ioctl_fiemap01 and mount03

Hi XiaoLei Wu,

Thank you for the patch. Review below.

> timestamps are not updated as expected under strictatime. Add ntfs3 to

Commit message looks good. The "Since commit ..." reference clearly
explains the motivation. Optionally, a formal:

  Fixes: 7dc8e9a515ce ("lib: Treat kernel ntfs3 as a separate FS")

trailer would aid automated tracking, though the inline reference is
acceptable per LTP convention.

Correct. ntfs3 is placed between the existing ntfs and tmpfs entries,
and matches the rationale: FIEMAP extent layout on ntfs3 does not match
the three-extent layout the test builds by writing at block offsets 0,
2, and 4.

Correct. ntfs3 is inserted immediately after the existing ntfs entry.
The commit message correctly identifies that test_strictatime() —
which calls test_file_dir_noatime(1, 1) expecting both file and
directory access times to be updated under MS_STRICTATIME — fails on
ntfs3 because the kernel ntfs3 driver does not update directory
timestamps as the Linux VFS expects.

Both tests are listed in runtest/syscalls. No Makefile changes are
needed since no new files are added.

--- Pre-existing issues (informational, do not affect verdict) ---

ioctl_fiemap01.c: verify_ioctl() allocates fiemap and buf via
SAFE_MALLOC, and opens fd via SAFE_OPEN, but only frees/closes them
at the function's end. If any SAFE_* macro in the middle aborts via
tst_brk(), the allocations are leaked for the duration of the
all_filesystems loop iteration. In practice this is harmless because
the mounts are torn down between iterations, but a .cleanup callback
closing fd would be cleaner. This is pre-existing and not introduced by
this patch.
