pin unix to already installed version
This prevents multiple versions of unix, from ghc and needed by newer
versions of some packages conflicting.

Had to update the bytestring and blaze-builder pins follow-on from this
change.

### Please describe the problem.
I'm trying to get an Android development environment set up, but I am running into conflicting library versions inside of the chroot. The package installation script now finishes, but I run into a link-time error during `cabal configure` because it is pulling in two different versions of the unix package for some reason. Please let me know if there is any information I can get from my build environment that would help diagnosing the issue.
### What steps will reproduce the problem?
Run `buildchroot`, `install-haskell-packages`, `make android`
### What version of git-annex are you using? On what operating system?
Attempting to build from source, cross-compiling for Android on Debian Jessie.
### Please provide any additional information below.
