Those files are not in fact symlinks, so it's clear that dpkg is confused
about something. Rather than debug dpkg, however, it's easier to just
drop __pycache__ directories. These hold the result of bytecode
compilation and are therefore optional, as Python will compile the sources
if the cache is not populated.
Fixes#6584.
