sys/shell/vfs: Use vfs_iter_mount_dirs instead of vfs_iter_mounts
...
This solves highly theoretical race conditions of file systems being
unmounted in an application while a shell `df` runs, fixes the previous
weird behavior that `/mountpoint/non-existant-path` could be df'd and
would even report that non-existant path as a file name, but more
practically ensures that an example of vfs_iter_mount_dirs is around.

tests: Cover vfs_iterate_mount_dirs in a new test
...
... adding precision to the documentation where a corner case was
discovered during testing and is permitted.
The test is too large for one small board, just like the other existing
VFS test.

sys/vfs: Drop per-filesystem fstatvfs
...
No current file system implements it, there is no defined semantic
difference between running fstatfs and the fallback currently
implemented, and there is practically no optimization gained from not
just running it through a single statvfs.

vfs: Document that open directories are counted

The addition is helpful because directories are visibly different from
open files (and generally are not treated like files).

vfs: Provide generic stat implementation (and use in fatfs)
...
When a file system has `fstat` and `open` implemented, `stat` can still
be missing. The new function is a generic implementation, and used in
fatfs to provide a `stat`.
