Subject: [PATCH] mount: add remote-fs dependencies if needed after change

This is an attempt to add it the remote-fs dependencies to a mount unit
if the options change, like when the utab options are picked up after
mountinfo has already been processed.  It just adds the remote-fs
dependencies, leaving the local-fs ones in place.

With this change I always get mount units with proper remote-fs
dependencies when mounted with the _netdev option.

(cherry-picked from a6d305f91d722e136c29222070efed5c5d8b120b)

Resolves: #1161417
