python-crypto: Remove package

Browse source 
The pycrypto package is not maintained; the last stable release was in
2013.

This also updates python3-cryptodome, from conflicting with
python3-crypto, to providing python3-crypto.

Subject: [PATCH] Throw exception when IV is used with ECB or CTR
The IV parameter is currently ignored when initializing
a cipher in ECB or CTR mode.
For CTR mode, it is confusing: it takes some time to see
that a different parameter is needed (the counter).
For ECB mode, it is outright dangerous.
This patch forces an exception to be raised.
