Add os.supports_dir_fd to test.pythoninfo

[encukou]

I looked for os.supports_dir_fd this when investigating the 3.13 Android failure on GH-158429, and realized we don't show it yet.
(So I need this and #146410 backported to 3.13, but, this PR should be useful even if that doesn't happen.)

• Split the attribute lists so the 'supports_*' names don't need to be repeated twice.

• Add 'supports_dir_fd'.

LGTM.

The variables are formatted/logged properly:

$ ./python -m test.pythoninfo|grep -E '^os\.(supports|name|supports_bytes_environ)'
os.name: posix
os.supports_bytes_environ: True
os.supports_dir_fd: ['access', 'chmod', 'chown', 'link', 'lstat', 'mkdir', 'mkfifo', 'mknod', 'open', 'readlink', 'rename', 'rmdir', 'stat', 'statx', 'symlink', 'unlink', 'utime']
os.supports_effective_ids: ['access']
os.supports_fd: ['chdir', 'chmod', 'chown', 'execve', 'listdir', 'pathconf', 'scandir', 'stat', 'statvfs', 'statx', 'truncate', 'utime']
os.supports_follow_symlinks: ['access', 'chown', 'link', 'stat', 'statx', 'utime']

Sorry @encukou, I had trouble completing the backport.

Please retry by removing and re-adding the "needs backport to 3.14" label.
