Giveback python-crypto on mips

[Andreas Rottmann <a.rottmann@gmx.at>]

Python-crypto failed to build on mips, due to failure installing the
(indirect) build dependency tex-common (tex-common bug #520714, but
really ucf bug #520626):

https://buildd.debian.org/fetch.cgi?&pkg=python-crypto&ver=2.0.1%2Bdfsg1-4&arch=mips&stamp=1237620531&file=log

So:

dw python-crypto_2.0.1+dfsg1-4 . mips . -m 'ucf (>= 3.0018)'
