OpenSSL 1.0.1j for gitian build process

see: https://www.openssl.org/news/secadv_20141015.txt

Changes gitian build scripts for linux and windows to use
OpenSSL 1.0.1j. osx scripts have other issues (they have not
been updated to dogecoin dependencies) so those will go into a
separate change.

Please note that although the input for qt-win.yml changes for
reasons of consistency, the output does not, so the version
number for qt-win*-5.2.0-gitian intermediates remain at r3.
