Simplify git-annex.cabal and generate sdist with make-sdist.sh.

The `cabal install` is happy as long as the files it needs are
present, but `cabal sdist` will only package up files you tell it to.
So, generate the source tarball ourselves.

The source tarball is generated by make-sdist.sh, which uses cabal
sdist to calculate the package name.  Could also generate the name
from the 'Version:' field in git-annex.cabal.
