Add python-crypto and python-openssl for rietveld uploads to work w/ oauth.
Add python-crypto and python-openssl for rietveld uploads to work w/ oauth.

In order for us to support OAuth-authenticated access to Rietveld, we
need to be able to generate signed authorization requests in the Rietveld
upload scripts. That requires us to have either the python OpenSSL wrappers
plus OpenSSL itself installed, or to use the python pyCrypto library.

Currently the bots use python-openssl, but don't work on Windows as a result.
We add the python-openssl wrapper to be consistent, but want to switch
to pycrypto, so once we have all the bots using pycrypto, we can drop
python-openssl from the list.
