bitbake: toaster: Add fake entry to Target_File for filesystem root

The files-in-image.txt file is produced by bitbake after an
image is created, listing all the files in the image.
However, this list doesn't include the root directory ('/').

buildinfohelper.py then tries to construct the filesystem
tree from this file, assuming that every directory apart from
the root directory (which is special-cased) can be assigned
a parent. But because the root directory isn't listed in
files-in-image.txt, an object for the root directory is never
created.

The direct subdirectories of the root ('./bin', './usr' etc.)
then can't be assigned a parent directory, as the object
representing the root directory doesn't exist. This
results in a Target_File lookup error and causes the
directory listing page to fail.

Fix this by creating a fake entry for the root directory
in the Target_File table, so that the direct subdirectories
of / can be assigned a parent. Note that it doesn't matter
that the root is faked, as its properties are never shown
in the directory structure tree.
