python3: base-nova compatibility

Browse Source 
The vfs is now populated with the python libs using a tar file system.
This is necessary because providing the zip from the rom did not work on NOVA.
The issue here is that python's zipimporter uses fseek with SEEK_END to
find the zip header. Unfortunately, the file size cannot be correctly
determined from the ROM session (see #1920) so that the fseek fails.
