filesystem: pass total_len to construct of when encoding file contents

Browse Source 
In our construct models we frequently use a context parameter "total_len",
we also pass this parameter to construct when we decode files, but we
do not pass it when we generate files. This is a problem, because when
total_len is used in the construct model, this parameter must be known
also when decoding the file.

Let's make sure that the total_len is properly determined and and passed
to construct (via pyosmocom).
