Jeffrey Finkelstein b6d1aa3e73 df: always produce the same order in output table
Change the `filter_mount_list()` function so that it always produces
the same order of `MountInfo` objects. This change ultimately results
in `df` printing its table of filesystems in the same order on each
execution. Previously, the table was in an arbitrary order because the
`MountInfo` objects were read from a `HashMap`.

Fixes #3086.
