tests: remove python_dependencies for smbserver from our tree

Users of the SMB tests will have to install impacket manually.

Reasoning: our in-tree version of impacket was quite outdated
and only compatible with Python 2 which is already end-of-life.
Upgrading to Python 3 and a compatible impacket version would
require to import additional Python-only and CPython-extension
dependencies. This would have hindered portability enormously.

Closes #5094
