[skyvault] Allow delete with SkyVault

If local storage is disabled but some local files are still left on the
device, these can be uploaded to the configured cloud storage or even
left on the device, depending on the admin policies. While the files
are still on device, MyFiles is temporarily turned into a read-only
volume (in the FilesApp). However, the users need to be able to delete
these files, e.g. before they're moved to the corp cloud.

This CL modifies the conditions for enabling the delete command/button
to account for the special SkyVault case. Any other actions are still
prohibited (creating new folder, pasting into this location...).
