[Dextrose] [PATCH][sugar] Copy .xo to removable device hack

[Martin Abente]

Plan Ceibal folks reported that it wasn't possible
to copy .xo files from datastore to removable
devices. This bug affects all versions of dextrose
and other distros based on sugar 0.88.1.

The problem was caused by a too generalist logic
at _check_for_bundle in which the journal was trying
to install bundles also when copying files to
removable devices.

This bug seems to be fixed in mainstream, but as side
effect of a big change to the journal code.

This patch checks for corner cases and avoid any attempt of
installation when copying .xo files to removable devices.

Version 2: Add alsroot suggestions.
