travis: Rename DOCKER_CMD to LINUX_CMD

The new name is arguably more informative, especially now
that we have MACOS_CMD and knowing that MINGW_CMD will
be introduced later on.

We still use DOCKER_CMD when calling Docker, and we assign
the actual script on a per-image basis. Having this
separation will help us when we introduce MinGW builds.
