Fix Ext2FilesystemTest unittests on Brillo.

The Ext2FilesystemTest tests use a set of pre-generated filesystems
stored in sample_images.tar.bz2 and attempt to parse those. This patch
installs the used filesystems in the same directory as the Chrome OS
test environment would generate those files, relative to the unittest
program executed: in a gen/ subdirectory.

Also, an empty filesystem that was previously created from the unittests
is now pre-generated.

The update_engine_unittests program now depends on those modules being
installed and those unittests pass.
