Add M2Crypto egg for 10.14 support

[Quantu]

Please add the M2Crypto egg for 10.14 to the mirror and the lines for including the 10.14 egg in the Makefile.

I'm not with Google so I can't modify the mirror, but I can tell you how to build it simply on a 10.14 system:

1. Install XCode and homebrew

2. brew install swig openssl

3. From https://pypi.org/project/M2Crypto, download and expand v0.22.3

4. Execute 'env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" SWIG_FEATURES="-cpperraswarn -includeall -I$(brew --prefix openssl)/include" python setup.py bdist_egg'

5. Rename the resulting egg to simian_M2Crypto-0.22.3-py2.7-macosx-10.14-intel.egg and place in root of simian

6. Modify the Makefile to account for this, under the 'm2crypto' section AND the various 'pkg' and 'dmg' build sections.

Notes: --build-from-source may be required for installing openssl with brew if a 10.14 bottle is not available. It may also be necessary to remove the dynamic openssl libraries or tweak linker options to force static during the swig build. You do NOT want dynamic links or it will not work on client machines.

I just duplicated the 10.13 egg and renamed it 10.14. Perhaps that's the worst idea ever, but ¯_(ツ)_/¯
