Install p7zip on DEPLOY=1 docker images and on MacOSX/Travis

On Ubuntu `7z` is available in the `p7zip-full` package.
On MacOSX it is in the `p7zip` formula.
On AppVeyor it is installed by default.

The `dist-*` and `cross` docker images build and deploy the dist
artifacts; the `x86_64-gnu-distcheck` docker image builds and checks
their sanity.
